Endoscopy from Kocher's Point Enabling Third Ventriculostomy and Pineal Biopsy

They might be treated by surgical resection or chemoradiotherapy according to the pathological diagnosis. As a minimally invasive initial treatment, an endoscopic approach from Kocher's point enables both third ventriculostomy and biopsy.
