Vertebral bodies and long limb bones were visualized. 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. 1. On x-rays the facet joints and interspinous distances are usually widened and the disk space may be narrowed. It is important to remember that the presence of fluid-fluid levels, although characteristic of aneurysmal bone cysts, is by no means pathognomonic, and is seen in other lesions as well, both benign and malignant (e.g. Aegerter and Kirkpatrick (11) proposed that the cause of the simple bone cysts is post-traumatic and posthemorrhagic, except the ones in the long bones. 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. Kitagawa T, Fujiwara A, Tamai K et-al. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The terms 'giant cell reparative granuloma of small bone'2,3 or 'giant cell lesion of small bone' have been discouraged 1. Search Main Page; Pub Med; Search Feeback (2009) ISBN:1604062266. Hence, we used all these three imaging techniques to make a complete diagnosis. 2002;179 (3): 667-9. On opening, a lesion containing fluid involving the spinous process was seen. The radiologic appearance of the lesion of our patient was not multiloculated and did not have fluid-fluid levels, blood degradation products, or soft tissue around the lesion. A case report and review of literature, Solitary bone cyst of the cervical spine--case report, Solitary bone cyst in the odontoid process and body of the axis. The pathogenesis of simple bone cysts is still unknown. This rare pathognomic radiologic finding is known as fallen fragment sign (12). The lesion appeared homogeneous and hyperintense on axial T2*-weighted images, and no blood degradation products were observed (Fig 4). Dawson EG, Mirra JM, Yuhl ET, Lasser K. Brodsky AE, Khalil M, VanDeventer L. Matsumoto K, Fujii S, Mochizuki T, Hukuda S. Park CK, Cho KK, Lee SW, Jeon JS, Kang JK, Choi CR. 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. Case 1, Axial CT scan of twelfth thoracic spine vertebrae. Epidural extension may also be detected. The exact pathogenesis of the lesion is unknown [2]. Thank you for your interest in spreading the word on American Journal of Neuroradiology. When . Majority of cases in the literature were treated surgically, including resection and curettage with or without bone grafting, and no recurrence has been reported (Table 1). 4.Tomaszewski KA, Saganiak K, Gadysz T, Walocha JA. The cyst will clearly appear as a bubble-like growth near a facet joint, which is a connection between vertebrae of the spine. 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.

The patient underwent surgery to remove the suspected simple bone cyst in the C4 vertebra. There are multiple internal septations with enhancement and fluid-fluid levels. Simple or solitary bone cysts (SBC) also known as unicameral bone cysts are benign lesions commonly seen in the peripheral skeleton [1]. Alanazi O, Alshebromi A, Albaz A, Bassi M. Thoracic Spine Aneurysmal Bone Cyst Causing Paraplegia in a Child: A Case Report. Corticosteroid injection had been described for lesion in the peripheral skeleton can be considered when the risk of fracture is low [30, 23]. 5. This is referred to as the doughnut signwhich results in increased uptake peripherally and a photopenic center. Gas measures about -580 to -1000 HU in density 3. Simple bone cyst (SBC) is not a common lesion in the spine and especially in the vertebral body. Cross-sectional imaging may be required when lesions are in unusual . Bone cysts have previously been considered a minor diagnostic criterion [2], but they are no . Most occur in children and adolescents. vertebral hemangioma is the most common spinal axis tumor. The bone scan showed a cold spot at the site of the lesion. Another suggestion is that venous obstruction of interstitial fluid drainage might be the cause (10). Unable to process the form. (2008) ISBN: 9780387755861 -, 5. They have been traditionally treated operatively with intralesional curettage or excision or complete en bloc excision with bone grafting are options 3. To the best of our knowledge, 21 cases of SBCs affecting the vertebra have been reported in the English literature. Additionally, CT can demonstrate fluid-fluid levels, which are harder to appreciate than on MRI and require viewing with a narrow window width 8. The laboratory tests including complete blood count, renal function tests, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, serum calcium, serum phosphorus and parathyroid hormone were all within normal limits. 1. Pediatr Radiol. 2004;25(7):1291-3. In this article we will discuss the differential diagnosis of well-defined osteolytic bone tumors and tumor-like lesions. The vertebral endplate capillaries are tiny branches of interosseous arteries that ramify throughout the vertebral body. Pain resolved; paresthesia improved and no recurrence. Osteoarthritis (OA) is the most common. Dhnert WF. The pain can. The physical exam was unremarkable, and no deformities nor neurologic alterations were noted. The bone scan was negative. 120 (Pt 1): 49-68. You can use Radiopaedia cases in a variety of ways to help you learn and teach. SBC is a rare benign lesion in the spine and it should be considered in the differential diagnosis when suggested by radiologic investigations. The introduction of bone cement into the vertebral body produces a sclerotic appearance on radiographs and CT, distinguishing this from the lucent appearance of . Roentgenography usually shows simple bone cysts as well-defined, intramedullary, metaphyseal, and pure lytic lesions. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Benign osteoporotic and malignant vertebral compression fractures have extremely different management and prognostic implications. Features on CT are similar to plain radiographs but CT has the advantage of characterizing extent, detecting radiograph-occult fractures, and assessing internal density (usually between 10-15 HU) 8. Q: What is the differential diagnosis of aneurysmal bone cysts? Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Most of the simple bone cysts are asymptomatic, unless they come with pathologic fracture. Our team of world-renowned neuroradiologists specializes in spinal and nerve diagnosis and interventions. The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. Figure 7-3 Sacral Aneurysmal Bone Cyst. (518) 262-3773. Clinical presentation is indistinguishable from disc herniation with sciatica and back pain the most common presenting symptoms 2. Enlarging vertebral body pneumatocysts in the cervical spine. 2016;36 (3): 801-23. Unable to process the form. 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. There was no recurrence. CT Considered the best method of diagnosis. UBCs can be rarely seen in adults in unusual locations such as in the talus, calcaneus, or the iliac wing. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Our goal was to present two cases of SBC who were referred to our department of spine surgery and review the literature. A large clear fluid-filled cavity was curetted and the cavity was filled with an autologous bone graft from iliac crest. Physical examination and laboratory tests were unremarkable with no neurologic deficit. Rare Tumors. Caro P, Mandell G, Stanton R. Aneurysmal Bone Cyst of the Spine in Children. Needle biopsies may be a problem because the material may consist of mostly blood elements. Results of three years follow-up. We do not capture any email address. at last follow-up male was well. There were no blood cells in its cavity and the characteristic morphology of an aneurysmal bone cyst in its wall was absent. 2.

Rapp T, Ward J, Alaia M. Aneurysmal Bone Cyst. The differential diagnosis depends on the modality. Soft Tissue and Bone Tumours. 2. Other studies described the prevalence of low bone mass in any site, lumbar spine, total body and femoral neck and/or total femur, despite of age below 20 years, and found higher prevalence from 23% to 68% 12 12 Dodd JD, Barry SC, Barry RB, Cawood TJ, McKenna MJ, Gallagher CG. They compose 28% of all skeletal hemangiomas, and the thoracic spine is the most frequent location. Active unicameral bone cysts occur most frequently between the ages of 1 and 10 years. . CONCLUSION. MAIN: : Radiology of the Spine. The most common differential diagnoses for SBC are aneurysmal bone cyst, brown tumor (hyperparathyroidism), infection and less commonly giant cell tumor. The cartilaginous layer is related to the nucleus pulposus and annulus fibrosus and has an important role in intervertebral disc nutrition 1. giant cell tumors (GCT), chondroblastoma, simple bone cystsand telangiectatic osteosarcomas). Vertebral body origin intraosseous hemangioma metastases Paget disease multiple myeloma osteonecrosis vertebral body osteomyelitis lymphoma plasmacytoma g. Differential diagnosis of vertebral lesions is very wide. show answer. 2014: 545017. Endplates Changes Related to Age and Vertebral Segment. Typically vertebral haemangiomas occur in the thoracic spine, specifically within the vertebral body. Giant cell tumors are expansile, lytic, locally aggressive, primary benign bone tumors with thinning of the cortex. The surgical intervention, when required, consists of primary closure of the dural defect through a posterior approach, accompanied by laminectomy and/or costotransversectomy.1 Although rare, arachnoid cysts can be a complication of Eur Spine J. (2006) European Spine Journal. Focal areas of high T1 and T2 signal 4 are also seen, presumably representing areas of blood of variable age (see aging blood on MRI).

He remained free of symptoms in the back and had a high level of sports activity. Disc cysts have been most commonly reported at the L4/5 level 1. 9.2 Large open cyst with multiple daughter vesicles inside The clear, yellow hydatid fluid contains sodium chloride, proteins, lipids, polysaccharides, and ions, having a neutral pH. Methods: An 86-year-old woman was referred to our spine service for a 2-year history of anterior thigh and leg pain. Those cysts predominantly occur in male patients with a ratio of 2.5:1. Felix S. Chew. Imaging technology precisely guides minimally invasive procedures with needles, catheters and other devices. They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer. Welcome VIN Logout World Neurosurg. There is vivid enhancement of the mass. Doughnut sign: increased uptake peripherally with a photopenic center. A: The association of radiological and histological findings makes the diagnosis of aneurysmal bone cysts. 5. 70% of patients have neurologic deficit. Embolization is another option 3. According to many authors, the lesions in the long bones are due to the developmental defect of the epiphyseal plate (4). The tumors may affect your spinal cord or the nerve roots, blood vessels, or bones of your spine. The end plates (zones of provisional calcification) maintain normal mineralization, and so appear strikingly dense compared to adjacent osteoporotic bone. Regarding the comparative study among CT and 3. . (2009) -, 3. show answer. Table 1 gives a summary of previously reported SBCs of the vertebral column in English literature [626]. 9).

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. Diagnostic Radiology: Musculoskeletal and Breast Imaging. Here an illustration of the most common sclerotic bone tumors. Emergency Medicine, Radiology 77 Providers. Our case reports the fifth simple bone cyst developing in cervical vertebrae. The stroma corresponds to septations with fibroblasts, spindle cells, osteoids, and numerous benign giant cells. 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. Zenmyo M, Komiya S, Hamada T, Inoue A.

Fisher CG, DiPaola CP, Ryken TC, Bilsky MH, Shaffrey CI, Berven SH, et al. A case report, Unicameral bone cyst of a lumbar vertebra. According to the radiologic findings, the lesion was identified as a simple bone cyst, and the diagnosis was verified by surgical and histopathologic examinations. We discuss the radiologic differential diagnosis of simple vertebral bone cysts, and the surgical and histopathologic verifications of the diagnosis are presented. AJR Am J Roentgenol. (2006) Proceedings (Baylor University. There was little bleeding. Lateral radiograph of the cervical vertebrae. MRI Imaging at 0.5 Tesla. Summary: Simple bone cysts are common, benign, fluid-filled, cystic lesions that occur mostly in the metaphysis of the long bones and are rarely found in vertebrae. The imaging evaluation includes computed tomography (CT), myelogra-phy and magnetic resonance imaging (MRI). If there is a fracture through this lesion a dependent bony fragment may be seen, and this is known as the fallen fragment sign. The imaging methods included radiography, whole-body bone scintigraphy (WBBS), CT and MRI. Two cases include a 24 year-old male and 26 year-old male with vertebral body lesion of T12 and L5 vertebrae,retrospectively. Providers Overview Location Reviews. .

Solid variant ABC of long tubular bones: A diagnostic conundrum for the radiologist. 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. We recommend SBC as a differential diagnosis in young patients with an unremarkable laboratory tests and suggestive imaging. [ 5, 6] Radiographs usually are adequate for diagnosis and for characterizing typical lesions. They commonly affect the long bones in children and adolescents [1]. Kumar B, Thirumal R, Chander S.

In the spine, the most typical site of localization is the sacrum; other vertebral segments are rarely involved (7). Providers Overview Location Reviews Providers Imaging in Oncology. Aneurysmal bone cysts (ABC) are benign expansile osteoclastic giant cell-rich bony neoplasms, composed of numerous blood-filled channels and cystic spaces 1. 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. CT (Fig 2) of the cervical spine showed the expansile unilocular cystic lesion of the spinous process at C4 and cortical thinning of the bone. 8. (2019) BioMed Research International. Although now generally considered as part of the vertebral body, historically they had been grouped with the intervertebral disc 3.

Internal signal heterogeneity, periosteal reaction and soft tissue edema can be seen in the setting of fracture 8. Spinal Cyst Treatment Conservative treatment may include rest, anti-inflammatory medications, painkillers, steroid injections and drainage. Vertebral metastasesare significantly more common than primary bone tumors, especially in an older patient or one with known primary disease elsewhere. Initially, the patient was treated conservatively but the pain did not improve. If the spine is affected, they may present with symptoms related to nerve root compression 1,3. subarticular zone stenosiswith nerve root compression. 9. Assessment of whether the bone lesions are sclerotic or lytic may help to narrow the differential diagnosis of primary disease if it is unknown. 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]. essential: simple cyst lacking a true lining with typical imaging features, desirable: fibrin-like deposits +/- mineralization forming cementum-like structures.
