Multidisciplinary Approach for Bone Metastasis: A Review. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts 2016;207(2):362-8. This is a routine medical imaging report. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), 8. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Notice the homogeneous thickening of the cortical bone. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. (2007) ISBN: 9780781779302 -. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. Well, generally, it means that it is due to a fairly slow-growing process. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Infections, a common tumor mimicker, are seen in any age group. 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. 2017;11(1):321. Notice the numerous predominantly osteoblastic metastases. This feature differentiates it from a juxtacortical tumor. You can then customize the above differential for whichever pattern of sclerosis that you see. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? Notice the numerous ill-defined osteoblastic metastases. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . 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). Common: Metastases, multiple myeloma, multiple enchondromas. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed. Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. 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. A molecular classification has been also proposed. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. J Korean Soc Radiol. Radiologe. (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 ). This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). ADVERTISEMENT: Supporters see fewer/no ads. Ask the patient or the clinician about this. Rib metastases may be osteolytic, sclerotic, or mixed. In the group of malignant small round cell tumors which include Ewing's sarcoma, bone lymphoma and small cell osteosarcoma, the cortex may appear almost normal radiographically, while there is permeative growth throughout the Haversian channels. 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. Many lesions can be located in both or move from the metaphysis to the diaphysis during growth. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. Bone Metastases: An Overview. CT 1. Bone and Joint Imaging. As part of the test, a healthcare professional takes a sample of the CSF In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. What does it mean that a lesion is sclerotic? Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 Here two other lesions in different patients that proved to be chondrosarcoma. 12. Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. The most common appearance is the mixed lytic-sclerotic. 2019;15:100205. Check for errors and try again. Ulano A, Bredella M, Burke P et al. . Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. The image shows a calcified lesion in the proximal tibia without suspicious features. CT can detect osteoblastic metastases with a higher sensitivity than plain radiographs and shines in the assessment of bones which are characterized by a small bone marrow cavity and a high amount of cortical bone such as the ribs 2,3. The image on the right is of a different patient who has an old NOF that shows complete fill in. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. 33.1b), CT scan axial images (c), and bone scintigraphy (d). Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. 4. Metastases are the most common malignant bone tumors. Osteoma consists of densely compact bone. 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. MRI of the sacrum: axial T1-weighted (T1w; Fig. There is reactive sclerosis with a nidus that is barely visible on the radiograph (blue arrow), but clearly visible on the CT (red arrows). Sclerotic bone lesions as a potential imaging biomarker for the diagnosis of tuberous sclerosis complex Authors Susanne Brakemeier 1 , Lars Vogt 2 , Lisa C Adams 2 , Bianca Zukunft 3 , Gerd Diederichs 2 , Bernd Hamm 2 , Klemens Budde 3 , Kai-Uwe Eckardt 3 , Marcus R Makowski 2 4 Affiliations These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Usually stress fractures are easy to recognize. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. 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. 7A, and 7B ). If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Even though plain X-ray and CT would typically be used to follow a suspected bone island, MRI was chosen as the follow-up modality because the sacrum is an area not well seen on plain films due to overlying bowel gas and concern regarding radiation dose from multiple CT scans to the pelvis of a 30-year-old woman. Classic ground glass appearance of the bone. The bone marrow compartment is not involved which is important for the surgical strategy. Less dense on CT and more heterogeneous than bone islands. Case 7: metastases from prostate carcinoma, Sclerotic bone pseudolesions - external artifact, bizarre parosteal osteochondromatous proliferation (Nora lesion), conventional intramedullary chondrosarcoma, dysplasia epiphysealis hemimelica (Trevor disease), solitary bone plasmacytoma with minimal bone marrow involvement, mixed lytic and sclerotic bone metastases, Lodwick classification of lytic bone lesions, Modified Lodwick-Madewell classification of lytic bone lesions. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. Bone metastases have a predilection for hematopoietic marrow sites: spine, pelvis, ribs, cranium and proximal long bones: femur, humerus. 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. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Acute osteomyelitis is characterised by osteolysis. 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. Mineralization in osteoid tumors can be described as a trabecular ossification pattern in benign bone-forming lesions and as a cloud-like or ill-defined amorphous pattern in osteosarcomas. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3 . Amsterdam: Elsevier; 1993. The mean and maximum attenuation were measured in Hounsfield units. They can affect any bone and be either benign (harmless) or malignant (cancerous). Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. 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. The major part of the lesion consists of reactive sclerosis. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. The MR image shows that the lesion has lobulated contours and nodular enhancement. A surface osteosarcoma could be considered in the differential diagnosis. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. Here a patient with a broad-based osteochondroma. However, cancers that metastasize to bone are very common. 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. A disadvantage of MRI is that the detection is poor in bones with a small marrow cavity such as the ribs and these bones are better investigated with CT 2,3. 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). 2016;207(2):362-8. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. 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.. Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Fundamentals of diagnostic radiology. 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. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. A periosteal reaction with or without layering may be present. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Strahlenther Onkol. SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Home. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. 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 . 2021;13(22):5711. Cancers (Basel). Mixed lytic/sclerotic lesion of right posterolateral 10 th rib, with extensive aggressive-appearing periostitis, as well as a multilobulated soft tissue component. The X-ray features were divided into two groups according to typical and atypical skeletal lesions. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. 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). CT-HU has stronger correlations with DEXA than MRI measurements. 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 Notice that many benign osteolytic lesions that are frequently seen in younger age groups may heal and appear as sclerotic lesions in the middle aged group. . Here, we showed that sBT values are higher in patients presenting 496 with bone loss . These lesions usually regress spontaneously and may then become sclerotic. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. 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. 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). Non-ossifying fibroma which has been filled in. There is no calcification and lesions may be expansile. Skeletal Radiol. Contact Information and Hours. There are calcified strands within the soft tissues. Benign periosteal reaction Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. 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. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. The lesion is predominantly calcified. 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. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Hall F & Gore S. Osteosclerotic Myeloma Variants. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. World J Radiol. T2-weighted MR image reveals a lobulated mass with high signal intensity. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. Radiological hallmark: formation of a chondroid (cartilagenous) matrix, which presents as punctuated, stippled or popcorn-like calcifications. 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. A sclerotic border especially indicates poor biological activity. Brant WE, Helms CA. Most of the time, sclerotic lesions are benign. Interventional Radiology). Bone scintigraphy can be either negative or show limited uptake. Unable to process the form. Click here for more examples of chondroblastoma. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. The radiographic appearance and location are typical. 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 this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. by Clyde A. Helms found incidentally on the imaging studies. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. Here an example of a patient with a stress fracture of the distal fibula. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. 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 ]. 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. (2007) ISBN:0781765188. MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M.

The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Imaging: W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet Sclerotic bone lesions appear exclusively in middle aged black patients. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. Both of these entities may have an aggressive growth pattern. Geode or subchondral cyst in the navicular bone, Geode or subchondral cyst in the tarsal bone, X-ray and MRI of a chondroblasoma in the tarsal bone, Chondromyxoid fibroma (CMF) in the calcaneus. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. . Radiographs are specific but suffer from low sensitivity 1. When a reactive process is more likely based on history and imaging features, follow-up is sometimes still needed. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. There are two kinds of mineralization: Chondroid matrix Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Mnemonic for multiple oseolytic lesions: FEEMHI: 33.1d). 4. 2020;60(Suppl 1):1-16. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Here an illustration of the most common sclerotic bone tumors. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. 7. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. 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. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. Most cases of chronic osteomyelitis look pretty nonspecific. 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. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). Polyostotic lesions These are inert filled-in non-ossifying fibromas. Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma.
