Abstract
|
|
|
|
Intralabyrinthine schwannomas are uncommon benign tumors that arise from neural elements within the labyrinth. These tumors produce otologic symptoms and signs of unilateral hearing loss, tinnitus or vertigo. Previously most cases were found only at autopsy or during surgery for intractable vertigo. Today, Gadolinium enhanced magnetic resonance imaging has made the diagnosis possible before surgical intervention. Optimal treatment was determined by the symptoms, tumor location and hearing. We report 1 case of intralabyrinthine schwannoma with a brief review of literatures.
