Clear cell variant of ependymoma is almost exclusively located in the supratentorial region. Only few cases of this tumor that located in the spinal cord have been reported. Here we report one case of intramedullary clear cell ependymoma of the lumbar spinal cord. In microscopic examination, the tumor cells were round to oval with moderate amounts of clear cytoplasm and centrally located lar...

Spinal cord cavernous angioma (SCAA) is a rare tumorous condition that can manifest various neurologic symptoms, and most lesions are needed to be removed surgically. However, since the SCAA positioned intramedullary, tumor resection could have modest risk for development of neuronal injury. Intraoperative neurophysiologic monitoring (IONM) has been widely accepted as an effective tool detectin...

Surgery is the best treatment to offer patients with an intramedullary spinal cord tumor. In experienced hands, radical surgery can be performed with acceptable surgical risks in most ependymomas, hemangioblastomas, and cavernomas and in 40% of astrocytomas. However, some inflammatory lesions may mimic an intramedullary tumor. That is the reason why, one should pay attention to spinal cord morp...
