Incidental Third Ventricular Chordoid Glioma: Case Report

Abstract

Chordoid glioma is a grade II (World Health Organization) rare type of brain tumor, frequently arising within the anterior part of third ventricle and/or suprasellar region, which can cause symptoms from obstructive hydrocephalus, local compression (as hypothalamic disfunction) or intracranial hypertension.We report an incidental case of 57-years-old woman, scheduled to a neurosurgery appointment due to an infundibular tumor, found on requested image after presenting unusual headaches and facial paresthesia. The tumor was totally resected by microsurgery via right pterional/trans-lamina terminalis approach without any postoperative morbidity. Histological analysis confirmed the unexpected chordoid glioma diagnosis.Chordoid glioma of the third ventricle is a rare tumor, which ideal treatment is surgical gross-total tumor removal. However, as it can carry a high risk of postoperative complications due to its location, one should make a careful and well-planed treatment decision on any case, especially in incidental and/or oligosymptomatic ones.
