Abstract

Intracranial lipomas are rare benign neoplasms accounting for <0.1% of all primary brain tumours. Most lipomas were incidentally detected by autopsy or computed tomography (CT).These slow growing benign lesions are usually asymptomatic and rarely require surgery. We report the case of a 70-year-old Nigerian woman who presented with persistent headaches following involvement in a road traffic accident 20 days previously. CT demonstrated a quadrigeminal cistern lipoma with no evidence of raised intracranial pressure or compression of neural structures. Her headaches resolved with conservative care. We describe the CT findings with a brief review of the literature.
