It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. These tumors are associated with genetic alterations that cause activation of the USP6 gene located at 17p13. The bone scan showed a cold spot at the site of the lesion. Such tumors can affect the spine, particularly the posterior elements. We discuss the radiologic differential diagnosis of simple vertebral bone cysts, and the surgical and histopathologic verifications of the diagnosis are presented. Unicameral bone cysts occur almost exclusively in children and adolescents (85%). The etiology of these discal cysts remains uncertain, but they are believed to occur due to traumatic disruption of the annulus with subsequent accumulation of fluid, which forms a surrounding pseudocapsule 1,2. X-ray and computed tomography (CT) characterize by expansile osteolytic lesions with thin sclerotic margins and fluid lines. Chang C, Garner H, Ahlawat S et al. Spinal aneurysmal bone cysts nearly always arise in the posterior vertebral arch but frequently extend into the ipsilateral pedicle and vertebral body, epidural space, or adjacent neural foramen (see Figs. Three iliac bones are identified, which articulate with the sacral vestige . About this product. CT and MR imaging were also used to determine the extent of the lesions and detect possible complications such as fractures. Haaga, John R. 1945-. Simple bone cysts are common, benign, fluid-filled, cystic lesions that cause minimal expansion of the bone and occur mostly in the metaphysis of long bones. The molecular criterion is the USP6 gene (at 17p13.2 locus) rearrangement. Simple bone cyst (SBC) is not a common lesion in the spine and especially in the vertebral body. At present, there is no gold standard for treatment for SBCs and Surgery may not be the optimal treatment for patients except for large lesions or pathologic fracture [21]. 2005;23(27):6756-62. Eur Spine J. Check for errors and try again. Musculoskeletal Imaging. show answer. When all of the radiologic findings were assessed, we concluded that the lesion had the characteristic radiologic appearance of a simple bone cyst. I suggest as others have that Cerebellar tonsillar ectopia as being trauma-induced and Arnorld Chiari 1 malformation to be congenital, though some would disagree. This may be followed up to detect any increase in the size, but there is no specific treatment. 8). Unicameral bone cysts are well defined geographic lucent lesionswith a narrow zone of transition,mostly seen in skeletally immature patients, which are centrally located and show a thin sclerotic margin in the majority of cases with no periosteal reactionor soft tissue component. Results Radiography detected 87.1% (27/31) of the lesions; WBBS demonstrated increased radionuclide activity in all the lesions. Aneurysmal bone cysts are multiloculated, expansile, highly vascular, osteolytic lesions that are filled with free-flowing blood products with fluid levels. Histologically aneurysmal bone cysts are characterized by the following 1,6: blood-filled cystic spaces separated by septa containing woven bone, bland fibroblasts, and multinucleated osteoclastic giant cells, the woven bone follows the border of the fibrous septa, bordered by osteoblasts. The only symptom reported by the patient was cervical pain irradiated to shoulders. The spinous process and the lesion within were removed. Our team of world-renowned neuroradiologists specializes in spinal and nerve diagnosis and interventions. Another suggestion is that venous obstruction of interstitial fluid drainage might be the cause (10). Roentgenography usually shows simple bone cysts as well-defined, intramedullary, metaphyseal, and pure lytic lesions. (2000) ISBN: 9780781725286 -, 4. In support of this theory is the fact that they are primarily encountered in young men, and are often hemorrhagic at surgery 1. Society of Skeletal Radiology- White Paper.

Herrero, Carlos Fernando P. S., Garcia, Sergio Britto, Garcia, Luis Vicente, Aparecido Defino, Helton Luiz. However in patients older than 40 years, while dealing with posterior element lesions, metastasis must always be kept in mind. The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. Winter, Raymond T. Morrissy et al. Sagittal T2-weighted and T1-weighted MR images of cervical vertebrae show the spinous process, unilocular, and homogeneous cystic lesion of the fourth cervical vertebra. Vertebral body origin intraosseous hemangioma metastases Paget disease multiple myeloma osteonecrosis vertebral body osteomyelitis Histologically, ABC is typically characterised by blood-filled cystic spaces separated by a spindle cell stroma with osteoclast-like giant cells and osteoid or bone production. WHO Classification of Tumours, 5th Edition. Lateral radiograph of the cervical vertebrae. Vertebral tumors can cause different signs and symptoms, especially as tumors grow. The imaging characteristics are otherwise non-specific. Providers Overview Location Reviews. Pathology report confirmed the diagnosis of SBC and the patient received no further treatment (Fig. 8.

New York Downtown Hospital is a medical group practice located in New York, NY that specializes in Physician Assistant (PA) and Diagnostic Radiology. CT scan of the thoracic spine reveals an osteolytic bony lesion involving T3 left posterior element and vertebral body, with a soft tissue mass resulting in cord compression. The reported peak is between 3 and 14 years of age, with the mean age at diagnosis being approximately 9 years. Parker J, Soltani S, Boissiere L, Obeid I, Gille O, Kieser D. 4. Case 1, (A): Anteriorposterior; (B): Lateral pre-operative X-ray. Skeletal Radiol. is seen in the vertebral body of L1 on axial T1-weighted (TR 285, TE 4.2) MRI (a), axial . Physical examination was unremarkable except for tenderness over the lower thoracic spine. Embolization is another option 3. Felix S. Chew. Curtis A. Dickman, Michael Fehlings, Ziya L. Gokaslan. The diagnosis of FIF was initially made preoperatively by the characteristic findings of imaging studies. The patient underwent surgery and the lesion was extracted through the right pedicle and the remaining cavity was filled with an autologous bone graft from the iliac crest and right-side posterior fusion was done from L4 to L5 (Fig. Its imaging diagnosis is usually difficult, . NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. On follow up, these lesions can change into fluid-filled cavities and eventually become granulation tissue 2. Computed tomography (CT) showed a multi-lobulated osteolytic lesion within the T12 body with extension to the right pedicle and transverse process (Fig. Computerized tomography scanning revealed a lytic lesion with sclerotic margins involving the left vertebral body, pedicle, lateral mass, and lamina of C-7 with an associated pathological compression fracture. The etiology and pathogenesis are unknown 8,10. General imaging differential considerations include 8,10: giant cell tumor of bone:usually older, extending to the articular surface, non-ossifying fibroma: eccentric, cortical base, aneurysmal bone cyst (ABC): usually eccentric, differential diagnosis of expansile lytic lesions without cortical destruction of bone. [2] According to one study, they have been identified in about 11% of patients at general autopsy. 43 New Scotland Ave, Albany NY, 12208. When . 18. Q: Which are the conditions associated with aneurysmal bone cysts? CT Considered the best method of diagnosis. Aneurysmal bone cysts are poorly vascular 10. A 26-year-old male presented with pain over the lower lumbar area. 2010;19 (10): 1621-6. spinal infection / inflammation / degeneration. Microscopic examination revealed mature fat cells, muscle fibers, and connective tissue fragments of the tendons that showed chondroid metaplastic foci (Fig 6A). Although Bloodgood first recognized simple bone cysts as a distinct disease entity in 1910, Jaffe and Lichtenstein (1) were the first to provide a detailed description of the simple vertebral bone cyst in 1942. The radiological report should include a description of the following 7: imaging characteristics e.g. 1. Current Diagnosis & Treatment in Orthopedics. They are common in patients younger than 30 years, with a slight female predominance. This condition is characterized by pain in the lower back and buttocks, and sometimes down the back of the legs. ADVERTISEMENT: Supporters see fewer/no ads. In a recent article, Zener, Alpert, and Klainer (1) reviewed two previously reported cases of sarcoidosis involving the vertebrae in which the diagnosis was established antemortem by biopsy and added a third of their own. Differential diagnosis of the spinal lesion can be narrowed by patients age, history, laboratory test, imaging studies and location of the tumor. Case 1, Axial CT scan of twelfth thoracic spine vertebrae. low lumbar region, which presents in its upper aspect a cystic multiloculated lesion with thin (5.9 mm) and . When aneurysmal bone cysts are found in vertebrae, they typically occur in the posterior elements, including the transverse process, spinous process, lamina, and neural arches. They are more common in males (M:F ~ 2-3:1) 2,6. On plain radiography (and to a lesser degree, CT), the differential diagnosis includes most of the lesions included in the mnemonic FEGNOMASHIC. 2. Simple bone cyst (SBC) is not a common lesion in the spine and especially in the vertebral body. . The main differential includes both lesions with intrinsic fluid-fluid levels (see fluid-fluid level containing bone lesions) and those from which an aneurysmal bone cyst may arise: osteosarcoma: especially telangiectatic osteosarcoma.
