A 26-year-old male presented with pain over the lower lumbar area. Unable to process the form. the six stages of vertebral development include: (1) gastrulation and formation of the somitic mesoderm and notochord, (2) condensation of the somitic mesoderm into somites, (3) formation of dermomyotomes and sclerotomes, (4) formation of membranous somites and re-segmentation with definitive vertebral formation, (5) vertebral chondrification and The neural arch is composed of bilateral pedicles, pars interarticularis, and laminae; from the neural arch arise the spinous process, bilateral transverse processes, and bilateral superior and inferior articulating processes. 1984;142(5):1001-4. Rarely, they are truly multiloculated, which can occur after repeated fractures 3,10. Vertebral pneumatocyst. Uncommon Manifestations of Intervertebral Disk Pathologic Conditions.

The interosseous arteries branch off segmental arteries (one per vertebra) which arise directly from the aorta. They are typically intramedullary and active cysts are found in the metaphysis of long bones, abutting the growth plate 1. Detection of associated intradiscal gas and communication between the vertebral and intradiscal gas can be demonstrated. They are more common in males (M:F ~ 2-3:1) 2,6. The most common differential diagnoses for SBC are aneurysmal bone cyst, brown tumor (hyperparathyroidism), infection and less commonly giant cell tumor. On plain radiography (and to a lesser degree, CT), the differential diagnosis includes most of the lesions included in the mnemonic FEGNOMASHIC. (2009) -, 3. The most frequent presentation is due to pathological fracture1,2,6. (2000) ISBN: 9780781725286 -, 4. World Neurosurg. When all of the radiologic findings were assessed, we concluded that the lesion had the characteristic radiologic appearance of a simple bone cyst. The histopathology showed a pattern compatible with an aneurysmal bone cyst. 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. Differential diagnosis of vertebral lesions is very wide. (2015) Folia morphologica. Rapp T, Ward J, Alaia M. Aneurysmal Bone Cyst.

Enter multiple addresses on separate lines or separate them with commas. Note the thinning of the cortical bone. 3). 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. AJNR Am J Neuroradiol. No complications were identified. Corticosteroid injection had been described for lesion in the peripheral skeleton can be considered when the risk of fracture is low [30, 23]. Vertebral lesion (differential). Lovell and Winter's Pediatric Orthopaedics. In the spine, the most typical site of localization is the sacrum; other vertebral segments are rarely involved (7).

The most common causes are inflammatory and demyelinating disorders like. 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. Although roentgenography is usually adequate to identify the simple bone cyst, CT and MR imaging should be used for diagnosis of lesions in anatomically complex locations such as the vertebrae. Physical examination and laboratory tests were unremarkable with no neurologic deficit. Our team of world-renowned neuroradiologists specializes in spinal and nerve diagnosis and interventions. Axial postcontrast T1-weighted MR image demonstrates similar signal intensity characteristics as those of precontrast T1-weighted images (not shown) that define nonenhancing lesions. They are mostly seen in children and adolescents, with ~80% under the age of 20 years 2,3but can occur at any age 1. 2. The most frequent sites are proximal humerus and proximal femur [1, 3].

In our cases, due to benign course of disease and imaging that suggested a benign lesion, we decided to do an open biopsy and definite surgery at the same time. Vertebral pneumatocysts are gas-filled cavities within the spinal vertebrae. Plain radiographs are the first-line imaging modality. The terms 'giant cell reparative granuloma of small bone'2,3 or 'giant cell lesion of small bone' have been discouraged 1. Simple or solitary bone cysts (SBC) also known as unicameral bone cysts are benign lesions commonly seen in the peripheral skeleton [1]. On opening, a lesion containing fluid involving the spinous process was seen. Our goal was to present two cases of SBC who were referred to our department of spine surgery and review the literature. Epidural extension may also be detected. They are recognized incidentally on radiographic examinations. 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. JCO. Thieme Medical Pub. 2022. The reported cases were more common in women (n=13, 61.9%) than men (n=8, 38.1%).
