Giant intracranial mucocele

Abstract

A 21-year-old man was admitted to hospital because of recent anosmia and liquorrhoea. He also complained of moderate headache and concentration problems in the past few years. On CT scan and MRI scans a big subfrontal process was seen, partially solid and partially cystic. Neurosurgical and histological findings proved that the lesion was an osteoma of the anterior skull base, concomitant with an intradurally extending mucocele.
