Primary Extracranial Meningioma of the Lacrimal Sac Fossa

Primary extracranial meningioma is a rare tumor, unlike its common intracranial counterpart. Infrequently found in the head and neck region, it can cause local or neurologic symptoms depending on its location and interaction with cranial nerves. While uncommon, it is an important diagnosis to have on the differential of periorbital lesions as surgical removal and prognosis are generally good. The authors present the first report of a patient with primary extracranial meningioma originating in the lacrimal sac fossa. Accepted for publication April 20, 2018.
