Radiology Grand Rounds XXII

Here is a case of Spinal ependymoma recuurence for the Radiology Grand Rounds submitted by Dr Sumer Sethi of Teleradiology Providers. Concept and Archive of the Radiology Grand Rounds is available at- Radiology Grand Rounds.

Pathology-Ependymomas are believed to account for 60% of all primary neoplasms of the spinal cord and filum terminale. Intraspinal ependymomas are most easily grouped into 3 classes: intramedullary lesions, myxopapillary ependymomas, and metastases from an intracranial origin. Intraspinal ependymomas are believed to arise from the ependymal cells lining the central canal, from the ventriculus terminalis of the conus, from within the filum terminale, or from cerebrospinal fluid (CSF) dissemination. xopapillary ependymomas arise almost exclusively in the region of the conus and filum terminale. They account for as many as 90% of tumors in the conus.

MRI-On T1-weighted images, ependymomas generally appear isointense relative to the normal cord, hyperintense relative to the normal cord on T2 weighted images. Ependymomas are and intensely enhancing with the administration of a gadolinium-based contrast material.
