A case of middle cranial fossa meningioma extending to the middle ear

Abstract

Meningioma is a benign tumor that arises from arachnoid cells and is said to easily develop along the distribution area of arachnoid granules. In our patient with a chief complaint of hearing loss, meningioma of the middle cranial fossa was considered to extend to the middle ear via the tympanic canopy. Our multidisciplinary skull base team performed mastoidectomy combined with the middle fossa approach in this case. The tumor in the middle cranial fossa and mastoid sinus was totally removed.
