Cysts associated with intramedullary ependymomas of the spinal cord: clinical, MRI and oncological features.

Purpose: Few published articles have explicitly focused on cysts associated with intramedullary (IM) ependymomas. The objective was to assess the clinical, MRI, and oncological results of patients operated for an IM ependymoma associated with a cystic portion.

Methods: During the study period, 23 IM tumors resected were cystic ependymomas.
