A solution to meningiomas at the trigone of the lateral ventricle using a contralateral transfalcine approach

Abstract

Background: Access to the trigone of the lateral ventricle is challenging because of the deep location and the intimate relationships to eloquent areas.

Methods: A novel posterior interhemispheric transfalx transprecuneus approach for two meningiomas at the trigone of the lateral ventricle is described.

Results: The meningiomas were resected completely with good neurologic outcomes and no operative mortality.

Conclusions: The feasibilities and advantages of this novel approach are discussed.
