Cavernous hemangiomas of the third ventricle: Alternative surgical routes in two cases.

Cavernous Hemangiomas (CH) arise from any part of the cerebrum. Intraventricular lesions are rare and pure third ventricular localization is rare for CHs. Cavernomas of the ventricles may present with bleeding or signs associated with hydrocephalus. Radical excision is advocated for optimal management of cavernomas. In the present study, we present two cavernomas of the third ventricle which were completely excised via interhemispheric transcallosal transforaminal and Sylvian approaches. Radical excision should be the aim of the surgeon since reoperation for residual cavernomas is more commonly associated with complications and poor outcome. Total excision should be the goal of the treatment due to risk of rebleeding or regrowth.
