sclerotic bone lesions radiologysclerotic bone lesions radiology

Metastases are the most common malignant bone tumors. Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. T2-weighted MR image reveals a lobulated mass with high signal intensity. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). For those that are possibly cancerous, a biopsy is conducted to identify it. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. MRI of the sacrum: axial T1-weighted (T1w; Fig. Click here for more examples of enchondromas. The mean and maximum attenuation were measured in Hounsfield units. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. Rib metastases may be osteolytic, sclerotic, or mixed. All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. 4.

Here, we showed that sBT values are higher in patients presenting 496 with bone loss . {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. It can identify small or large tumors, multiple sclerosis (MS), encephalitis (brain inflammation), or meningitis (inflammation of the meninges that lie between the brain and the skull). Osteoid osteoma (2) Sclerosis is present from either tumor new bone formation or reactive sclerosis. Park S, Lee I, Cho K et al. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Oncol Rev. The contour of the involved bone is usually normal or with mild expansive remodelling. Osteochondroma is a bony protrusion covered by a cartilaginous cap. In order to classify osteolytic lesions as well-defined or ill-defined, we need to look at the zone of transition between the lesion and the adjacent normal bone. Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. DD: old SBC. The role of imaging in SN lymphomas is to identify the primary site of disease, site for biopsy and to map the lesion in its entirety in cases of patients undergoing radiotherapy [ 15, 21 ]. The benign type is seen in benign lesions such as benign tumors and following trauma. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Radiology. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. Malignant transformation Age: most commonly seen in 10-25 years, but may occur in older patients. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. A chondrosarcoma was diagnosed at biopsy. To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Therefore, MRI and bone scan were performed. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Here a lesion located in the epi- and metaphysis of the proximal humerus. This could very well be an enchondroma. The use of radiological imaging in medical care dates back to 1895 when Complete envelopment may occur.

Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. One of the first things you should notice about sclerotic bone lesions is whether they are single and focal, multifocal, or diffuse. Here two other lesions in different patients that proved to be chondrosarcoma. There are two kinds of mineralization: Chondroid matrix Usually it is a lesion of childhood or young adults. Polyostotic lesions > 30 years Based on the morphology and the age of the patients, these lesions are benign. Macedo F, Ladeira K, Pinho F et al. BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. Interventional Radiology). Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. The illustration on the left shows the preferred locations of the most common bone tumors. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. This represents a thick cartilage cap. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. Concerning the above factors the differential diagnosis includes the following lesions 1-3: sclerotic bone metastasis: might be solitary because no others are present or have been imaged, infection: e.g. The most common appearance is the mixed lytic-sclerotic. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Here some typical examples of bone tumors in the spine. Check for errors and try again. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Continue with the MR-images. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. 7A, and 7B ). 33.1d). It is a feature of malignant bone tumors. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Central location most common with some expansion and cortical thinning. After an injury, different types of fluid can build up in a bone. 105-118. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail.

Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. Here a rather wel-defined eccentric lesion which is predominantly sclerotic. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. Skeletal Radiol. Notice how easily MRI depicts these lesions. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Coronal MR image demonstrates subtle low intensity line representing the fracture. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . The diagnosis was fibrous dysplasia. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. However, a specific density range has not been specified for those terms 1. This part corresponds to a zone of high SI on T2-WI with FS on the right. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Peripheral chondrosarcoma, arising from an osteochondroma (exostosis).

Notice that CT depicts these lesions far better (red arrows). These lesions were possibly misinterpreted as new when applying WHO criteria. 1988;17(2):101-5. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Centrally there is an ill-defined osteolytic area. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE - The Lancet Oncology Clinical Picture | Volume 24, ISSUE 3, e144, March 2023 Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE Prof Ruchi Mittal, MD Debashis Maikap, MD Pallavi Mishra, MD 3. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Fundamentals of Skeletal Radiology, second edition Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. 2019;15:100205. This feature differentiates it from a juxtacortical tumor. As you can see, by just dropping the items that tend to cause generalized sclerosis, we have generated a fairly good differential for focal lesions. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. 11. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? (2007) ISBN:0781765188. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Most common malignant bone tumor, which is almost always low-grade, Primary sites of origin: proximal long bones, around knee, pelvis and shoulder girdle, usually central and metaphyseal. Strahlenther Onkol. Notice that in all three patients, the growth plates have not yet closed. Purpose: To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. 6. It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. Materials and Methods 4 , 5 , 6. In juxta-articular localisation, the reactive sclerosis may be absent. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. . On the left three bone lesions with a narrow zone of transition. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Fundamentals of diagnostic radiology. In the epiphysis we use the term avascular necrosis and not bone infarction. 1991;167(9):549-52. Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 In an older patient one should first consider an osteoblastic metastasis. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Nancy M. Major, Clyde A. Helms and William J. Richardson. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Here images of a patient with breast cancer. Journal of Bone Oncology. A bone island larger than 1 cm is referred to as a giant bone island (12). Conclusion. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Osteosarcoma (2) They usually affect posterior vertebral elements and their number and size increase with age. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Many important signaling . CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. 2021;216(4):1022-30. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. 2, The primary utility of the bone scan is that if there is no increased uptake, sclerotic metastatic disease is highly unlikely; therefore, the lesion can be considered most likely a bone island and follow-up radiographic imaging obtained. mutation, and both sclerotic and lytic bone lesions together for the first time. There were other features that favored the diagnosis of a low-grade chondrosarcoma like a positive bone scan and endosteal scalloping of the cortical bone on an MRI (not shown). These are infections and eosinophilic granuloma. Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. The major part of the lesion consists of reactive sclerosis. Some prefer to divide patients into two age groups: 30 years. 2017;11(1):321. Location within the skeleton Cancers (Basel). Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. Ulano A, Bredella M, Burke P et al. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Small area of lucency with adjacent sclerosis at the distal right medial femoral metaphysis that could relate to enthesopathic change or remodeling of a fibroxanthoma of bone.. About Us; Staff; Camps; Scuba. Click here for more detailed information about NOF. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). Sclerosis can also be reactive, e.g. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. SWI:low signal intensity on the inverted magnitude and phase images 9. You can then customize the above differential for whichever pattern of sclerosis that you see. More uniform cortical bone destruction can be found in benign and low-grade malignant lesions. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Frequently encountered as a coincidental finding and can be found in any bone. Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Both imaging modalities achieved only a moderate correlation with DEXA. 2015;7(8):202-11. AJR 2000; 175:261-263. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Moreover, questions such as the . Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. Eosinophilic Granuloma and infections should be mentioned in the differential diagnosis of almost any bone lesion in patients < 20 years. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. Rapid growth of the mineralized mass is not uncommon. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. Most bone tumors are solitary lesions. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Osteoblastic metastases (2) Infection is seen in all ages. The signal intensity on MR depends on the amount of calcifications and ossifications and fibrous tissue (low SI) and cystic components (high SI on T2). Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Click here for more examples of chondroblastoma. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. AJR 2005; 185:915-924. Lippincott Williams & Wilkins. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. Differential diagnosis 1. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Infection with a multilayered periosteal reaction. 2016;207(2):362-8. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. 7. Home. Mnemonic for multiple oseolytic lesions: FEEMHI: Most cases of chronic osteomyelitis look pretty nonspecific. Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Radiologic Atlas of Bone Tumors Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. The subchondral bone is key to cartilage and joint health. AJR Am J Roentgenol. Well, generally, it means that it is due to a fairly slow-growing process. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. Here an illustration of the most common sclerotic bone tumors. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. ADVERTISEMENT: Supporters see fewer/no ads. A periosteal reaction with or without layering may be present. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. WSI digital slide: https://kikoxp.com/posts/4606. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). A high grade chondrosarcoma must be considered in the differential diagnosis. Edema often present in the surrounding bone marrow. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. World J Radiol. General Considerations Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . Here CT-images of a patient with prostate cancer. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Sclerotic bone metastases. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time.
