Fourney DR, Frangou EM, Ryken TC, Dipaola CP, Shaffrey CI, Berven SH, et al. The vast majority of discal cysts, as rare as they are,have been reported in males (M:F 9:1), typically of Asian ethnicity 1,2. Treatment is not always required and discal cysts have been reported to spontaneously regress 1. They rarely extend into the nearby ribs or adjacent vertebrae. Case 1, (A): Axial T2-weighted MR image of twelfth thoracic spine vertebrae; (B): Sagittal T2-weightedimages of thoracic spine vertebrae. The terms 'giant cell reparative granuloma of small bone'2,3 or 'giant cell lesion of small bone' have been discouraged 1. Until now, to our knowledge, only 10 cases of a simple bone cyst involving the vertebrae have been reported, with four of them in the cervical vertebrae. vertebral hemangioma. In the case of our patient, the lesion did not cause any such fracture in the bone. MR imaging shows an expansile mass involving the T3 left-sided posterior arch and vertebral body, destroying the lamina and pedicle with epidural extension. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-70932. Unable to process the form. In the case of our patient, the radiologic findings were not suggestive of a giant cell tumor, because the cystic lesion was not destructive or aggressive and did not have multiple compartments or heterogeneous signal intensity and blood degradation products on MR images. JMSR. Ilaslan H, Sundaram M, Unni K. Solid Variant of Aneurysmal Bone Cysts in Long Tubular Bones: Giant Cell Reparative Granuloma. They have been traditionally treated operatively with intralesional curettage or excision or complete en bloc excision with bone grafting are options 3. The synovial cyst is a lesion that can be treated by z-joint intra-articular injections as an alternative to surgery. 2004;24 (8): 1707-10. The previously termed 'giant lesion of small bones' features the same morphological features as the solid subtype of aneurysmal bone cyst 1. 5).

Imaging technology precisely guides minimally invasive procedures with needles, catheters and other devices. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. In general, vertebral pneumatocysts are less common than intraosseous pneumatocysts in the pelvis, especially adjacent to the sacroiliac joint. If large and threatening to fracture, or causing deformity then an intralesional steroid injection can be performed 3-5. Telehealth services available. Intervention is usually not required for an asymptomatic lesion. Skeletal Radiol. 17. Welcome, VIN Public! Rapp T, Ward J, Alaia M. Aneurysmal Bone Cyst. The recurrence rate of 15-30% has been described 3. Gas measures about -580 to -1000 HU in density 3. 120 (Pt 1): 49-68. There have been 21 cases of SBCs in English literature, and only 8 cases have been reported in the vertebral body. 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. 19 (4): 423-4. Case 2, Sagittal T2-weighted and T1-weighted MR images of lumbar vertebrae show the body and homogeneous cystic lesion of L5. A, Chondroid metaplastic foci in the connective tissue surrounding the lesion (hematoxylin-eosin stain 100). 6. Vertebral hemangiomas (VHs) are the most common benign tumors of the spine. Discal cysts (also known as a disk cyst or disc cyst) are uncommon lesions of the spine, representing an extrathecal cyst which communicates with the adjacent intervertebral disc through an annular fissure. Yamamoto T, Yoshiya S, Kurosaka M et-al. Curtis A. Dickman, Michael Fehlings, Ziya L. Gokaslan. The cysts are of a variable signal, with a surrounding rim of low T1 and T2 signals. Symptoms. imaging (MRI). 9. Rai A & Collins J. Percutaneous Treatment of Pediatric Aneurysmal Bone Cyst at C1: A Minimally Invasive Alternative: A Case Report. . The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. UBCs can be rarely seen in adults in unusual locations such as in the talus, calcaneus, or the iliac wing. Soft Tissue and Bone Tumours. In the spine, the most typical site of localization is the sacrum; other vertebral segments are rarely involved (7). show answer. Case 1, Axial CT scan of twelfth thoracic spine vertebrae. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. [1] Usually benign, this lesion is of vascular origin and like hemangiomas in other parts of the body usually involves a proliferation of normal capillary and venous structures. and lack of fusion of the vertebral body of L1-L2. Vertebral pneumatocysts are gas-filled cavities within the spinal vertebrae. Search Main Page; Pub Med; Search Feeback Aneurysmal bone cysts consist of multiloculated blood-filled spaces of variable size separated by fibrous septa,surrounded by a thin reactive bone formation rich in multinucleated osteoclast-like giant cells 1. occupying most of the height of the L2 vertebral body (Figure 2). . Breakage of a cyst can trigger an immunological reaction from the host, sometimes leading to an anaphylactic shock. Any other prior symptoms are mild pain, local tenderness, and swelling (5). Vertebral hemangiomas are an incidental and relatively common radiological finding and a benign tumor of vascular origin. 4. Corticosteroid injection had been described for lesion in the peripheral skeleton can be considered when the risk of fracture is low [30, 23]. Unicameral bone cyst. Benign osteoporotic and malignant vertebral compression fractures have extremely different management and prognostic implications. The diagnosis of this lesion is possible by a combination of typical radiological and pathological features. An otherwise healthy 26-year-old female patient presented with a 1-year history of neck pain radiating to both upper extremities. Needle biopsies may be a problem because the material may consist of mostly blood elements. CT Considered the best method of diagnosis. Doughnut sign: increased uptake peripherally with a photopenic center. Usually, diagnosis of SBC disease is based on pathologic confirmation due to its rarity and non-specific clinical presentation. 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. Musculoskeletal Imaging. Unicameral bone cysts were initially described by the German pathologist Rudolf Virchow in 1891 8,9. The diagnosis of this lesion is possible by a combination of typical radiological and pathological features 1-6. Most patients are between 20 and 40 years old. This study presents two cases of spinal SBC managed surgically with no recurrence in long-term follow-up. Our case reports the fifth simple bone cyst developing in cervical vertebrae. 1). They may occur in all parts of the skeleton and particularly involve the metaphysis of long bones (5, 7) but occasionally involve spine, especially cervical and thoracic regions. It should be stated that if any sign of malignant lesion was encountered, the surgery would have stopped and only biopsy would have been performed. 74 (2): 157-68. giant cell tumors (GCT), chondroblastoma, simple bone cystsand telangiectatic osteosarcomas). Considered the best method of diagnosis. a multicystic bone lesion with fluid-fluid levels on imaging. 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. show answer. Thieme Medical Pub. Department of Radiology of the Medical University of Vienna, Austria and Rijnland hospital in Leiderdorp, the Netherlands In this article we will focus on spinal cord diseases that are characterised by high signal within the cord on T2WI. New York Downtown Hospital is a medical group practice located in New York, NY that specializes in Physician Assistant (PA) and Diagnostic Radiology. 5. MRI can demonstrate the characteristic fluid-fluid levels exquisitely, as well as identify the presence of a solid component and concerning features suggesting an aneurysmal bone cyst-like appearance of another tumor entity. Fig. 1. Kransdorf M & Sweet D. Aneurysmal Bone Cyst: Concept, Controversy, Clinical Presentation, and Imaging. Two cases include a 24 year-old male and 26 year-old male with vertebral body lesion of T12 and L5 vertebrae,retrospectively. 3 These . Q: How are spine aneurysmal bone cysts diagnosed? Aneurysmal bone cyst. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. A: The differential diagnosis of aneurysmal bone cysts is giant cell tumor, chondroblastoma, chondromyxoid fibroma, osteoblastoma, eosinophilic granuloma, and telangiectatic osteosarcoma. Vertebral bodies and long limb bones were visualized. The physical exam was unremarkable, and no deformities nor neurologic alterations were noted. Results Radiography detected 87.1% (27/31) of the lesions; WBBS demonstrated increased radionuclide activity in all the lesions. Saeid Safaei, Mirbahador Athari, Parisa Azimi, Ahmadreza Mirbolook, Taravat Yazdanian, Farhad Hamzehzadeh, Simple bone cyst of spinal vertebrae: two case reports and literature review, Journal of Surgical Case Reports, Volume 2021, Issue 11, November 2021, rjab507, https://doi.org/10.1093/jscr/rjab507. CT Axial non-contrast 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. Posterior spinal fusion was performed with instrumentation with pedicle screws from T10 to L2 and a mixture of autologous bone graft and allograft was used to achieve better fusion (Fig. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. The reported peak is between 3 and 14 years of age, with the mean age at diagnosis being approximately 9 years. The teardrop fragment comes from the anteroinferior aspect of the vertebral body. Although they have been described in most bones, the most common locations are 3-5: typically eccentrically located in the metaphysis, especially femur, proximal tibia and fibula, and humerus, especially posterior elements of the spine with extension into the vertebral body in 40% of cases 5, short bones of hands and feet: more often with a central location, craniofacial: jaw, basisphenoid, and paranasal sinuses, epiphysis, epiphyseal equivalent,or apophysis: rare but important. Note the thinning of the cortical bone. Diehn FE, Maus TP, Morris JM et-al.

The tumor has a heterogeneous appearance on both T1 and T2-weighted MR, with focal areas of high T1 signal, presumably representing blood. show answer. Vertebral Lesions: Imaging Algorithm 1 Algorithm 2 Initial imaging usually consists of plain radiography. The diagnosis of spinal SBC may be difficult and delayed until operative treatment when it is confirmed by histological assessment. Vertebral body mass: differential diagnosis, Differential diagnosis of a vertabral body mass, 1. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). 21 this benign vascular tumor of the vertebral body, often discovered incidentally on imaging, can be associated with vertebral body collapse and epidural extension with spinal cord compression; on rare occasions, it may exhibit aggressive growth. Medical Center). 2). Front Page; Message Boards; Search. 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. The bone scan was negative. The patient had no recurrence seven years after surgery. Regarding the comparative study among CT and ADVERTISEMENT: Supporters see fewer/no ads. Unable to process the form. 1. Lippincott Williams & Wilkins. elementary radiological lesions include angular lesions of the vertebral body, non-specific spondylodiscitis (very similar to infectious forms), osteolytic lesions with varying degrees of collapse of the vertebral body (visible lesions even in childhood), osteosclerosis of one or more vertebral bodies with development of hyperostosis, 9. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-23773. Giant cell tumors of the spine only accounts for 37% of primary bone tumors. at last follow-up male was well. 14. When all of the radiologic findings were assessed, we concluded that the lesion had the characteristic radiologic appearance of a simple bone cyst. When . 1995;164(3):573-80. [3] These lesions are usually an incidental finding . The radiological report should include a description of the following 7: imaging characteristics e.g. A systematic approach is useful for recognizing tumors of the spine with characteristic features such as bone island, osteoid osteoma, osteochondroma, chondrosarcoma, vertebral angioma, and aneurysmal bone . Simple Bone Cyst in Spinous Process of the C4 Vertebra. Those cysts predominantly occur in male patients with a ratio of 2.5:1. Methods: An 86-year-old woman was referred to our spine service for a 2-year history of anterior thigh and leg pain. Iowa Orthop J. Thank you for your interest in spreading the word on American Journal of Neuroradiology. MRI of Bone and Soft Tissue Tumors and Tumorlike Lesions. 4.Tomaszewski KA, Saganiak K, Gadysz T, Walocha JA. Aneurysmal bone cysts commonly present with pain and swelling. In this study, we describe the computed tomography (CT) features of pulmonary laceration in a study population, which included 364 client-owned dogs that underwent CT examination for thoracic trauma, and compared the characteristics and outcomes of dogs with and without CT evidence of pulmonary laceration. the sacroiliac joint. We do not capture any email address. The patient underwent surgical resection of the tumor. As the lesion becomes inactive it migrates away from the growth plate (normal bone is formed between it and the growth plate) and it gradually resolves 3,5. Three iliac bones are identified, which articulate with the sacral vestige . A single vertebral surgical approach for spinal extradural meningeal cysts spanning multiple vertebral segments by auxiliary neuroendoscope. SUMMARY: Vertebral compression fractures are very common, especially in the elderly. Broadly, these lesions can be separated into: aneurysmal bone cyst(<2%): neural arch (60%); vertebral body (40%), Brown tumor(an osteoclast reaction in hyperparathyroidism). Therese J Bocklage, Robert Quinn, Berndt Schmit et al. (2008) ISBN: 9783131354211 -. Steven P. Meyers. A: Surgical resection or curettage of the tumor and bone graft with or without adjuvant treatment, including cryotherapy, sclerotherapy, radionuclide ablation, radiotherapy, selective arterial embolization, and minimally-invasive intervention radiology treatment. In some instances, surgery with curettage and bone grafting is required. Lumbar X-ray showed mild height loss and fracture of the superior endplate of T12 vertebra (Fig. 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.
