A Rare Case of Subependymoma of the Septum Pellucidum as Intratumoral Hemorrhage
2015
Subependymomas (SEs) are rare, benign, noninvasive, slow-growing tumors located anywhere along the ventricular walls. They arise most frequently in the fourth ventricle followed by the lateral ventricle, and less frequently in the septum pellucidum, third ventricle, and spinal cord. Most SEs are found incidentally at autopsy, but some may produce clinical symptoms. Tumor-related hemorrhage represents an extremely rare presentation sign. We describe a rare case of septum pellucidum SE as tumoral hemorrhage. The tumor was totally removed via an interhemispheric transcallosal approach. Histological examination found typical SE. Although the patient had transient memory impairment, he had a good postoperative course and was discharged on the twenty-first postoperative day.
