Minimally invasive techniques: full endoscopic inferior parietal lobule approach for an endoventricular removal of a left trigone meningioma grade I

Intraventricular meningiomas are rare tumors, mainly localized in the lateral ventricle trigone. Several microscopic surgical approaches have been proposed according to the location of the tumors in the atrium. The authors present the case of a 68-year-old woman who had an increscent medically resistant headache with a left trigone meningioma. In the video, they demonstrate the four-hands surgical technique through a minimally invasive fully endoscopic retractor-less transcortical approach. They also discuss the background of these tumors and the technical nuances of the procedure, including the differences between an endoscopic surgical and a microsurgical one.
