Primary oligodendroglioma of the septum pellucidum

The oligodendroglioma is an infrequent cerebral tumor of glial ancestry. It is even rarer when primarily arising within the confines of the ventricles and particularly if originating from the septum pellucidum. A 22-year-old man harboring a primary oligodendroglioma of the septum pellucidum was successfully treated by intraventricular tumor removal through a left transcortical-transventricular approach, using microsurgical technique. A brief review of relevant data about both intraventricular oligodendrogliomas and tumors of the septum pellucidum is presented.
