Neuronavigation-guided Endoscopic Endonasal Excision of Schwannoma-like Chordoma of Meckel’s Cave: A Case Report

Abstract

Chordomas are locally aggressive malignant tumors due to their recurrence potential and originate from embryonic notochordremnants. Chordomas can originate anywhere on the axial skeleton. They are extradural and spread by bone destruction. Chordomasare locally aggressive tumors that invade the dura mater, and may also present with secondary intradural growth. The Meckel’s cavelocation of chordomas has been very rarely reported in the literature. Chordomas located in Meckel’s cave can be radiologicallyconfused with trigeminal schwannomas. Herein, we report a case of Meckel’s cave chordoma that was successfully excised throughneuronavigation-guided endoscopic endonasal excision, a technique commonly used in skull base surgeries.
