Abstract

Epidermoid tumours are non-neoplastic inclusion cysts representing up to 1.1 per cent of all intracranial tumours, typically presenting with symptoms related to pressure or intracranial rupture in the fourth or fifth decade of life.

The authors present a case of a parasellar epidermoid cyst which has ruptured in to the nasopharynx; to the best of their knowledge, this has not been previously reported.

The computed tomography (CT) and magnetic resonance imaging (MRI) are presented. The pathology and radiological features of epidermoid tumours are discussed, particularly in relation to extracranial connections. The differential diagnosis of lesions eroding the central skull base is reviewed.
