One of the first things you should notice about sclerotic bone lesions is whether they are single and focal, multifocal, or diffuse. 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. Growth of osteochondromas at adult ages, which is characterized by a thick cartilaginous cap (high SI on T2WI) should raise the suspicion of progression to a peripheral chondrosarcoma. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. The benign type is seen in benign lesions such as benign tumors and following trauma. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. A periosteal reaction with or without layering may be present. Impact of Sclerotic. Osteoid matrix {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. This could very well be an enchondroma. Radiographic features that should raise the suspicion of malignant transformation on plain radiographs or CT include: Here the reactive sclerosis is the most obvious finding on the X-ray. Complete envelopment may occur. Notice that the cortical bone extends into the lesion. 2014;71(1):39. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. 7. . Moreover, questions such as the . D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. Diffuse bony sclerosis (mnemonic). Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. Not infrequently encountered as coincidental finding at later age. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. Bone scintigraphy (99mTc MDP) is very sensitive for the detection of osteoblastic providing information on osteoblastic activity but suffers from specificity with a false-positivity rate ranging up to 40% 1. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Therefore, MRI and bone scan were performed. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 1991;167(9):549-52. 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. World J Radiol. Skeletal Radiol. (2007) ISBN: 9780781779302 -. The image shows a calcified lesion in the proximal tibia without suspicious features. Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. Less dense on CT and more heterogeneous than bone islands. It is most commonly located in the outer table of the neurocranium or in a paranasal sinus. These are infections and eosinophilic granuloma. This could be an osteoblastic metastasis or an osteolytic metastasis that responded to chemotherapy. Fundamentals of Skeletal Radiology, second edition Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. by Clyde A. Helms A chondrosarcoma was diagnosed at biopsy. Ossifications or calcifications can be present in variable amounts. 14. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 Presentation: pain, mass, pathologic fracture. It can also be proven histologically. 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. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. A molecular classification has been also proposed. Check for errors and try again. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. Here a patient with a broad-based osteochondroma. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Both imaging modalities achieved only a moderate correlation with DEXA. Teaching Point: Metastasis is the most common malignant rib lesion. You can then customize the above differential for whichever pattern of sclerosis that you see. However, cancers that metastasize to bone are very common. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Infections, a common tumor mimicker, are seen in any age group. Polyostotic lesions > 30 years In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Enchondroma, the most commonly encountered lesion of the phalanges. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. Macedo F, Ladeira K, Pinho F et al. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. One can then apply various features of the lesions to this differential, and exclude some things, elevate some things, and downgrade others in the differential. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. J Korean Soc Radiol. Fisher C, DiPaola C, Ryken T et al. Melorrheostosis is a dysplasia of the bone, characterized by apposition of mature bone on the outer or inner surface of cortical bone. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. Many important signaling . The bone marrow compartment is not involved which is important for the surgical strategy. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). MR usually shows a large amount of reactive changes in bone and soft tissue. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. (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 ). In juxta-articular localisation, the reactive sclerosis may be absent. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Click here for more examples of chondrosarcoma. Ulano A, Bredella M, Burke P et al. Occasionally slowly enlargement can be seen. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. 13. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. The lesion shows increased uptake of the tracer in the bone scan (arrow in Fig. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Edema often present in the surrounding bone marrow. Most bone tumors are solitary lesions. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. I think that the best way is to start with a good differential diagnosis for sclerotic bones. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Office Phone: (517) 205-6750. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. The subchondral bone is key to cartilage and joint health. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. (2005) ISBN: 9780721602707 -. In the cases in which the solitary sclerotic lesion has increased, uptake on bone scan, follow-up CT, or plain film imaging is recommended at 3-, 6-, and 12-month intervals. Osteosarcoma with interrupted periosteal rection and Codman's triangle proximally (red arrow). 2018;10(6):156. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. 10. Society of Skeletal Radiology- White Paper. Usually new bone is added to one side of the cortex only. Some prefer to divide patients into two age groups: 30 years. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. 2017;11(1):321. Here a rather wel-defined eccentric lesion which is predominantly sclerotic. Strahlenther Onkol. Biopsy revealed dedifferentiated chondrosarcoma. 2021;50(5):847-69. This is a routine medical imaging report. Radiological atlas of bone tumours of the Netherlands Committee on Bone Tumors Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. Here CT-images of a patient with prostate cancer. The radiographic appearance and location are typical. Unable to process the form. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . 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). The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. Sclerotic bone lesions appear exclusively in middle aged black patients. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. Enhancement after i.v. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. The contour of the subchondral bone plate was maintained until day 3, but it was absorbed just under the cartilage defect from day 7 to 14. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). Here are links to other articles about bone tumors: Most bone tumors are osteolytic. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Clin Orthop Relat Res. 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. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M.

(white arrows). Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition Benign periosteal reaction For those that are possibly cancerous, a biopsy is conducted to identify it. Acute osteomyelitis is characterised by osteolysis. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. 2. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . It grows primarily into the surrounding soft tissues, but may also infiltrate into the bone marrow. Here images of an osteosarcoma in the right femur. About Us; Staff; Camps; Scuba. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. 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. Here images of a patient with prostate cancer. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Particularly chronic osteomyelitis may have a sclerotic appearance. Click here for more detailed information about NOF. 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. Generic Differential Diagnosis of Sclerotic Bone Lesions. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. 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). Unable to process the form. Bone and Joint Imaging. These lesions were possibly misinterpreted as new when applying WHO criteria. brae in keeping with diffuse bone infarcts. Materials and Methods 2 ed. 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. When considering trauma as a cause for sclerotic lesions, remember to check and see if the areas involved are areas in the typical distribution for stress fractures. 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. Chrondroid tumors are more frequently encountered than bone infarcts. Ossification in parosteal osteosaroma is usually more mature in the center than at the periphery. AJR 2005; 185:915-924. Osteoblastic bone metastases are characterized by increased bone formation 2. (2007) ISBN:0781765188. Skeletal Radiol. In some cases however the osteolytic nidus can be visible on the radiograph (figure). There are two kinds of mineralization: Chondroid matrix Malignant transformation Based on the morphology and the age of the patients, these lesions are benign. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them.

ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Urgency: Routine. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The differential diagnosis of bone lesions that result in bony sclerosis will be given. 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. AJR Am J Roentgenol. Radiographs are specific but suffer from low sensitivity 1. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered In the epiphysis we use the term avascular necrosis and not bone infarction. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). Most of the time, sclerotic lesions are benign. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. A brain MRI can . 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 33.1b), CT scan axial images (c), and bone scintigraphy (d). One study, using a mean attenuation of 885 HU and a maximum attenuation of 1,060 HU as cut-off values, distinguished the higher density bone islands from lower density osteoblastic metastases with 95% sensitivity and 96% specificity. Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. Here a patient with a mineralized mass in the soft tissues. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Check for errors and try again. CT-HU has stronger correlations with DEXA than MRI measurements. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. This feature differentiates it from a juxtacortical tumor. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. Bone metastases have a predilection for hematopoietic marrow sites: spine, pelvis, ribs, cranium and proximal long bones: femur, humerus. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. 33.1d). These lesions are not osteochondromas, but consist of reactive cartilage metaplasia. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. -. 2010;35(22):E1221-9. Rib metastases may be osteolytic, sclerotic, or mixed. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. 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. Here two other lesions in different patients that proved to be chondrosarcoma. A sclerotic border especially indicates poor biological activity. : Radiopaedia is free thanks to our supporters and advertisers manifestations of CGL with AGPAT2 mutation multifocal,., Pialat J, Clzardin P.
