AbstractIntramedullary tumors constitute approximately 5% of spinal tumors and about 80% are of neuroglial origin. We reviewed our series of adult patients with spinal neuroglial intramedullary tumors operated on between 1984 and 2011 at the neurosurgical department of Bicêtre hospital. The histopathological records for 196 patients were retrospectively analyzed. The majority of tumors were ependymomas (68%) and astrocytomas (27.5%). The importance of a proper and detailed neuropathological diagnosis is the key to define patient management. The available literature data about the genetic profiles of these rare tumors are summarized and reviewed.
