These are infections and eosinophilic granuloma. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. They can affect any bone and be either benign (harmless) or malignant (cancerous). Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. Skeletal Radiol. Enhancement after i.v. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. . The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia.. On MR imaging bone infarcts are characterized by irregulair serpentiginous margins with low signal intensity on both T1 and T2 WI and with intermediate to high fat signal in the center part. Growth has been demonstrated well after skeletal maturity. How should one approach sclerotic bone disease? In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Park S, Lee I, Cho K et al. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. 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 ]. Generic Differential Diagnosis of Sclerotic Bone Lesions. 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 Diffuse bony sclerosis (mnemonic). Aggressive periosteal reaction 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. The differential diagnosis of bone lesions that result in bony sclerosis will be given. However, cancers that metastasize to bone are very common. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Bone marrow edema can happen with fractures and other serious bone or joint injuries. 9. Differentiating between a diaphyseal and a metaphyseal location is not always possible. An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. Less dense on CT and more heterogeneous than bone islands. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. in Ewing's sarcoma or lymphoma. (see diagnostic imaging pearls). 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). Notice that in all three patients, the growth plates have not yet closed. The epiphysis, metaphysis and diaphysis may be involved. 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. On the left three bone lesions with a narrow zone of transition. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Usually one bone is involved. Here Melorrheostosis of the ulna with the appearance of candle wax. Donald Resnick, Mark J. Kransdorf. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. 2021;216(4):1022-30. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. 1.

Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Conclusion. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. Here an example of a patient with a stress fracture of the distal fibula. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. 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. Sometimes a more solid periosteal reaction is present combined with cortical thickening and broadening of the bone. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Amsterdam: Elsevier; 1993. This represents a thick cartilage cap. There are calcified strands within the soft tissues. On the right T2-WI with FS of same patient.. Rib metastases may be osteolytic, sclerotic, or mixed. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. The benign type is seen in benign lesions such as benign tumors and following trauma. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Here a patient with a broad-based osteochondroma. (2007) ISBN:0781765188. Based on the morphology and the age of the patients, these lesions are benign. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. by Mulder JD et al Several genes have been discovered that, when disrupted, result in specific types . Bone scintigraphy can be either negative or show limited uptake. There are two kinds of mineralization: Chondroid matrix Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. Check for errors and try again. Most bone tumors are solitary lesions. 1991;167(9):549-52. 2018;2018:1-5. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. Click here for more detailed information about fibrous dysplasia. This is consistent with the diagnosis of a reactive process like myositis ossificans. Click here for more examples of enchondromas. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details. Wide zone of transition 2020;60(Suppl 1):1-16. 2022;51(9):1743-64. None of the patients had undergone prior treatment for the metastases. 5. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. They usually affect posterior vertebral elements and their number and size increase with age. 2 ed. Sclerotic metastases arise from . Urgency: Routine. mutation, and both sclerotic and lytic bone lesions together for the first time. Multiple enchondromas are seen in Morbus Ollier. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. 2017;11(1):321. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk).

Rohrmann, Jr., M.D., Endowment for Radiology Resident Educational Excellence, Michael and Rebecca McGoodwin Endowment for Radiology Resident and Fellow Training and Education, The Norman and Anne Beauchamp Endowed Fund for Radiology. The lesion shows increased uptake of the tracer in the bone scan (arrow in Fig. The lesion is predominantly calcified. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). 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. 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 or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. Interventional Radiology). You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. 1988;17(2):101-5. Radiologic Atlas of Bone Tumors Hall F & Gore S. Osteosclerotic Myeloma Variants. -. Most primary bone tumors are seen in patients In patients > 30 years we must always include metastases and myeloma in the differential diagnosis. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. 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. After an injury, different types of fluid can build up in a bone. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-22391. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Sclerosis can also be reactive, e.g. Diagnostic brain imaging tests can assess bone fractures, structural problems, blood vessel abnormalities, and changes in brain metabolism. 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. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. 33.1d). Publicationdate 2010-04-10 / update 2022-03-17. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. The bone marrow compartment is not involved which is important for the surgical strategy. Usually stress fractures are easy to recognize. In the case of benign, slowly growing lesions, the periosteum has time to lay down thick new bone and remodel it into a more normal-appearing cortex. Bone islands can be large at presentation. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. (2007) ISBN: 9780781779302 -. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Here some typical examples of bone tumors in the spine. Etiology Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3 . However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. 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. 12. 2016;207(2):362-8. J Korean Soc Radiol. Arthritis Rheum., 42 (2012), pp. However, these lesions are often underreported, mainly because the subject is not well known to general radiologists who struggle with the imaging approach and disease entities. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). Sarcoidosis is a multi-system disease with a range of . AJR 2000; 175:261-263. Fundamentals of diagnostic radiology. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. MRI of the sacrum: axial T1-weighted (T1w; Fig. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. 5 Biopsy should be considered in atypical cases or in high-risk patients with primary malignancies associated with osteoblastic metastatic disease. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. 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. Imaging: 2019;15:100205. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 Ask the patient or the clinician about this. In the subchondral bone, the number of TRAP-positive cells peaked on day 14. However, a specific density range has not been specified for those terms 1. 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. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. 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. 13. Well, generally, it means that it is due to a fairly slow-growing process. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. 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).
