Oligodendroglioma CT

Introduction

Overview

Overview

Head CT scan may be helpful in the diagnosis of oligodendroglioma. Findings on CT scan suggestive of oligodendroglioma are round or oval, marginated, hypo- to isodense mass with hemorrhage, ribbon-like calcification, ill-defined enhancement following intravenous contrast administration, pressure erosion/remodelling of overlying skull, and marked ventricular enlargement suggestive of hydrocephalus.
