Transcallosal interforniceal approach for removing the medial type of thalamic gliomas

Abstract

To report an approach for removing the medial type of thalamic gliomas. Eight cases of medial type of thalamic gliomas, 4 males and 4 females, aged 22 (14 approximately 53), underwent resection of the tumor by transcallosal interforniceal approach: right frontal craniotomy, along the cerebral midline natural cleft to reach the third ventricle. By using microsurgical skill, subtotal removal of the tumors was achieved in 5 cases and partial removal was achieved in 3 cases with satisfactory postoperative effects. Keeping the fornix, thalamus, midbrain, and internal cerebral vein intact with few complication and good outcome, transcallosal interforniceal approach is an ideal way to resect the medial type of thalamic gliomas.
