Eighth Cranial Nerve Lipoma Manifesting as Intractable Vertigo —Case Report—

Abstract

A 49-year-old female presented with an extremely rare lipoma of the cerebellopontine angle (CPA) manifesting as intractable vertigo and tinnitus. Subtotal removal of the lipoma was performed to debulk the tumor and decompress the cranial nerve VIII. Her complaints were resolved without new neurological deficit. We recommend surgery in patients with symptomatic CPA lipomas for diagnosis, debulking, and decompression of cranial nerves to relieve the symptoms. © 1995, The Japan Neurosurgical Society.
