A Case of Meningioma Invading the Middle Ear / 대한이비인후과학회지

ABSTRACT

Frequency of meningioma is reported to be 18 percent of all incidences of intracranial primary tumors, and tumor extension to the extracranial structures occurred in about 20 percent of intracranial meningiomas. Involvement of the middle ear is quite rare and meningioma in the middle ear can be seen either as a primary tumor or an extension of intracranial tumors. Since predominant symptoms of meningioma are hearing loss, otorrhea and other otologic symptoms, one can be mislead to chronic otitis media with diagnosis. Recently, we incidentally found a meningioma in the middle ear during chronic ear surgery in a 40-year-old female, who was confirmed by histopathologic diagnosis to have meningioma. We report herewith this case with the review of literatures.
