Intracochlear Schwannoma: A Rare Lesion
Journal Title: BMH Medical Journal - Year 2016, Vol 3, Issue 1
Abstract
Intralabyrinthine schwannoma is a rare cause of sensorineural hearing loss and intractable vertigo. Schwannoma is a benign neoplasm of the nerve sheath. Acoustic schwannomas can arise anywhere along the entire course of the eighth cranial nerve, usually from intracanalicular portion of either the inferior or superior division of vestibular nerve. Intralabyrinthine schwannoma arises primarily from intralabyrinthine branches of the eight cranial nerve and initially have no component in the internal auditory canal (IAC). We report a case of a young lady with left sided progressive hearing loss. Magnetic resonance imaging of cochlea documented intralabyrinthine schwannoma (intracochlear type). She underwent surgery and histopathology confirmed the diagnosis of schwannoma.
