title: Neurilemmoma of the frontal-ethmoid sinus simulating a mucocele. A case report.
abstract: A 48-year-old black female had a 1-year history of increasing proptosis and headache. Sinus films and CT scan demonstrated an expansive soft tissue mass in the right frontal-ethmoid sinus with lateral displacement of the medial orbital wall, consistent with a mucocele. Resection revealed a solid tumor which was identified pathologically as a neurilemmoma. To our knowledge, this is the first published report of a frontal-ethmoid neurilemmoma presenting solely with proptosis, and also mimicking a mucocele.
