Bilobed Prepontine White Epidermoid Cyst Camouflaged as Tubercular Abscess: A Case Report

Abstract

Epidermoid cysts are ectodermally derived benign extra-axial lesions that have typical imaging characteristics following cerebrospinal fluid (CSF) signal intensity, but occasionally show unusual hyperintensity on T1-weighted images (T1WI), known as white epidermoid, thus posing a diagnostic challenge. We report an unusual case of bilobed prepontine white epidermoid masquerading as tuberculous abscess in a known case of tubercular meningitis.
