Interhemispheric transcallosal transforaminal approach to benign lesions located anteriorly in the third ventricle: case series

Abstract

Benign or malignant masses located in the third ventricle may present with various clinical signs. In this paper, we report three cases of colloid cyst and a rare cavernous hemangioma located in the third ventricle. This infrequent localization of cavernous hemangioma was discussed under the light of the lesions' clinical and radiological features, and the outcomes of the interhemispheric transcallosal transforaminal surgical approach. Interhemispheric transcallosal and transforaminal approach is a safe route for total excision of benign lesions, such as colloid cyst and cavernous hemangioma, which are located anteriorly in the third ventricle.
