Recurrent extracranial sinonasal meningioma presenting 27 years after complete surgical eradication of right frontal meningioma.

A 79-year-old man presented to our department with nasal obstruction and postnasal drip. On examination he had unusual bilateral nasal polyps, which were histologically diagnosed as meningioma. Twenty-seven years earlier he had undergone successful removal of a right frontal meningioma. A CT scan performed 7 years after his primary surgery had shown complete excision with no evidence of recurrence. Extracranial meningiomas are rare tumours and are usually extensions from an intracranial mass lesion. We document what we believe to be the first case of an extracranial meningioma, presenting as nasal polyps, 27 years after successful surgical eradication of the primary lesion.
