The tumor has a heterogeneous appearance on both T1 and T2-weighted MR, with focal areas of high T1 signal, presumably representing blood. AJNR Am J Neuroradiol. This may be followed up to detect any increase in the size, but there is no specific treatment. 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. B, Lamellar and spongy bone fragments containing bone marrow elements (hematoxylin-eosin stain 40). 5). There was little bleeding. Check for errors and try again. The vertebra is divided anatomically into the vertebral body anteriorly and the neural arch posteriorly. [2] According to one study, they have been identified in about 11% of patients at general autopsy. The end plates (zones of provisional calcification) maintain normal mineralization, and so appear strikingly dense compared to adjacent osteoporotic bone. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Hacking C, Weerakkody Y, et al.

They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer. 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. 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. Kumar B, Thirumal R, Chander S. Aneurysmal Bone Cyst of Thoracic Spine with Neurological Deficit and Its Recurrence Treated with Multimodal Intervention A Case Report. 2004;25(7):1291-3.

Axial postcontrast T1-weighted MR image demonstrates similar signal intensity characteristics as those of precontrast T1-weighted images (not shown) that define nonenhancing lesions. Unicameral bone cysts (UBC),also known as simple bone cysts (SBC) are common benign non-neoplastic lucent bony lesions that are seen mainly in childhood and typically remain asymptomatic. Percutaneous treatment with fibrosing agents has also been performed, either in isolation or as a precursor to surgical excision 3,11,12. Aydin S, Abuzayed B, Yildirim H et-al. Bone cysts have previously been considered a minor diagnostic criterion [2], but they are no . They are recognized incidentally on radiographic examinations. Hammoud S, Weber K, McCarthy E.

The lesion can be categorized according to the bone reporting and data system as Bone-RADS 4 unless histology has been already obtained 7. Note the thinning of the cortical bone. The molecular criterion is the USP6 gene (at 17p13.2 locus) rearrangement. Lateral radiograph of the cervical vertebrae. 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. In addition, predominantly mature compact bone and focal spongious bone fragments containing bone marrow elements were seen (Fig 6B). 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. On MRI, the differential is much shorter, especially when age, location and plain film appearance are taken into account. We present a simple bone cyst involving the C4 vertebra of a 26-year-old female patient. Patients may present with pain, paresthesias, paraplegia, motor deficits, sphincter impairment, and myelopathy. mri Axial T2 Sagittal T2 Sagittal STIR Sagittal T1 Sagittal T1 fat sat Axial T1 C+ Sagittal T1 C+ MRI Axial T2 The introduction of bone cement into the vertebral body produces a sclerotic appearance on radiographs and CT, distinguishing this from the lucent appearance of . Lung laceration occurred in 46/364 dogs with thoracic trauma (prevalence 12.6%). MR signal characteristics for an uncomplicated lesion include 8,10: Fluid-fluid levelscan be seen in the setting of fibrous septations, which can enhance 8. 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. Dogs . These tumors are associated with genetic alterations that cause activation of the USP6 gene located at 17p13. Herrero, Carlos Fernando P. S., Garcia, Sergio Britto, Garcia, Luis Vicente, Aparecido Defino, Helton Luiz. 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 We recommend SBC as a differential diagnosis in young patients with an unremarkable laboratory tests and suggestive imaging. 1981;136(6):1231-2. Case 2, Sagittal T2-weighted and T1-weighted MR images of lumbar vertebrae show the body and homogeneous cystic lesion of L5. MAIN: : Radiology of the Spine. Although now generally considered as part of the vertebral body, historically they had been grouped with the intervertebral disc 3. Surg Neurol Int. 2). In younger patients with vertebral body lesions most likely diagnosis is histiocytosis, whereas the lesions involving posterior elements of the spine may have ABC, Osteoblastoma, and Tuberculosis as differentials. 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. During the active phase, the cyst remains adjacent to the growth plate. Epidural extension may also be detected. Management of SBC of the spine is not well described. Simple bone cysts are common, benign, fluid-filled, cystic lesions that cause minimal expansion of the bone and usually occur in the metaphysis of long bones.

These rearrangements also occur in the aneurysmal bone cysts of the hand and feet but not in lesions of the jawbones 1. Imaging technology precisely guides minimally invasive procedures with needles, catheters and other devices. 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, They may cause expansion of the bone with thinning of the overlying cortex. Case 1, Axial CT scan of twelfth thoracic spine vertebrae. Aneurysmal bone cysts are benign giant cell-rich lesions of unknown cause and are sometimes difficult to distinguish from other bone tumors 1-6. A large clear fluid-filled cavity was curetted and the cavity was filled with an autologous bone graft from iliac crest. Vertebral tumors can cause different signs and symptoms, especially as tumors grow. Lumbar X-ray showed mild height loss and fracture of the superior endplate of T12 vertebra (Fig. Radiographs and nonenhanced CT images show lytic lesions producing cortical thinning and expansion with a destructive sacral or vertebral mass.

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. CT proved to be more useful in the initial assessment and measurement of progress of this disease than conventional radiography and myelography. A soft tissue mass is often present. 1. . Haithcock JA, Layton KF, Opatowsky MJ. Roentgenographic and CT views indicate an osteolytic lesion that results in an expansion and thinning of the surrounding cortical bone. The etiology and pathogenesis are unknown 8,10. Physical examination was unremarkable except for tenderness over the lower thoracic spine. 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. They may occur in any bone, most commonly long bones. The spinal column is not a common site for SBC [4]. The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. Assessment of whether the bone lesions are sclerotic or lytic may help to narrow the differential diagnosis of primary disease if it is unknown. AJR Am J Roentgenol. 1). Epidemiology 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.

They are typically intramedullary and active cysts are found in the metaphysis of long bones, abutting the growth plate 1. Another suggestion is that venous obstruction of interstitial fluid drainage might be the cause (10). Skeletal Radiol. The spinous process and the lesion within were removed. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Botz B, Lukies M, et al. 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. Most patients are between 20 and 40 years old.

The lateral view of radiographs of the cervical vertebrae demonstrated a faintly visible osteolytic lesion causing minimum expansion in the C4 vertebral spinous process (Fig 1). Although not completely understood, some authors believe a vertebral pneumatocyst is an extension of intradiscal gas (vacuum phenomenon) 1. Vertebral Lesions: Imaging Algorithm 1 Algorithm 2 Initial imaging usually consists of plain radiography. Unable to process the form. Benign osteoporotic and malignant vertebral compression fractures have extremely different management and prognostic implications. Giant cell tumors are expansile, lytic, locally aggressive, primary benign bone tumors with thinning of the cortex. Regarding the comparative study among CT and Most of the simple bone cysts are asymptomatic, unless they come with pathologic fracture. The imaging characteristics are otherwise non-specific. Logout.
