title: [A case of subependymoma of the septum pellucidum].
abstract: A 72-year-old-female was admitted because of slight disorientation and urinary incontinence. CT scan on admission revealed isodensity mass in the portion of the septum pellucidum and dilated lateral ventricle with patcy enhancement. A patient underwent the right frontal osteplastic craniotomy and subtotal removal of the tumor. Microscopical examination of the removed tumor tissue revealed a typical finding of subependymoma. In the previous literature subependymoma of the septum pellucidum has been reported only seven cases. We reported a rare case of subependymoma derived from the septum pellucidum, and histopathology and symptomatology of the tumor were discussed with the literature.
