MR appearance of acquired spinal epidermoid tumors.
نویسندگان
چکیده
Intradural epidermoid tumors occur more often in patients with a history of one or more lumbar punctures (1-4). It is hypothesized that they result from skin fragments introduced into the thecal sac during lumbar puncture and that they differ from the congenital heterotopic lesions. This report details the characteristic patient history , the water-soluble myelographic findings, and the MR appearance of this lesion , with pathologic confirmation.

MR imaging of a spinal epidermoid tumor.
Primary epidermoid tumors are congenital lesions of ectodermal origin. Their appearance has been described with MR and CT in the calvarium (1-7]. Primary and secondary epidermoid tumors of the spine are rare tumors , and their MR appearances have not been described. We present a case of epidermoid tumor of the spinal canal that probably was caused by a lumbar puncture performed approximately 20...
متن کاملA Rare Intramedullary Epidermoid Cyst of the Thoracic Spinal Cord: Case Report and Review of Literature
Epidermoid cyst in the spinal cord is a rare condition. It constitutes of only 0.6-1.1% of all spinal tumors. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region.We report a forty-two -year-old female who presented with left extremity radicular pain and myelopathy. MRI of the thoracic spine,illustrated a focal fusiform enlargement of the tho...
متن کاملQuantitative MR evaluation of intracranial epidermoid tumors by fast fluid-attenuated inversion recovery imaging and echo-planar diffusion-weighted imaging.
BACKGROUND AND PURPOSE Quantification of MR can provide objective, accurate criteria for evaluation of a given MR sequence. We quantitatively compared conventional MR sequences with fast fluid-attenuated inversion recovery (fast-FLAIR) and echo-planar diffusion-weighted (DW) MR imaging in the examination of intracranial epidermoid tumors. METHODS Eight patients with surgically confirmed intra...
متن کاملDiffusion-weighted MR imaging of the brain: value of differentiating between extraaxial cysts and epidermoid tumors.
This study demonstrates the use of diffusion-weighted MR imaging in improving the specificity of the diagnosis of extraaxial brain tumors. Three surgically proved lesions (one arachnoid cyst and two epidermoid tumors) and two nonsurgically proved lesions (arachnoid and ependymal cysts) were evaluated with T1- and T2-weighted spin-echo studies followed by intravoxel incoherent motion (IVIM) MR i...
متن کاملA rare case of intradural and extramedullary epidermoid cyst after repetitive epidural anesthesia: case report and review of the literature
BACKGROUND Spinal epidermoid cysts are benign tumors, which are rarely seen as an intradural extramedullary spinal cord tumor in the conus medullaris region. Acquired spinal epidermoid cysts are mostly caused by iatrogenic procedures, such as lumbar puncture, and the majority of acquired spinal epidermoid cysts have been reported below the L1 level, because lumbar puncture is usually performed ...
