Third ventricle glioblastoma. Case report and review of literature

Abstract

A glioblastoma presenting as a solitary third ventricle mass is exceptional.

Case description: We report the case of a 29-year-old woman who lost consciousness, was taken to hospital and referred a previous history of depression and diabetes insipidus. Magnetic resonance imaging study revealed a heterogeneous anterior third ventricle mass with ring enhancement after contrast administration. It was approached and subtotally resected by a transcortical-transventricular route and histological diagnosis proved it to be a glioblastoma. There are only two other similar well-described cases and another nine have been previously reported in surgical series of high grade gliomas and glioblastomas. The possible origin of this lesion is discussed.
