Schwannoma, also called neurilemmoma, is a benign neoplasm of peripheral nerve sheath. An infrequent location of a multiple intraoral plexiform schwannoma arising on the branches of the facial nerve in the vestibular mucosa of a young male patient is here discussed. Surgical treatment has been discussed on the base of histological findings and diagnosis.

PURPOSE Although headache in vestbibular schwannoma (VS) is uncommon as an initially presenting symptom, headache in VS is usually associated with tumor growth due to various factors, especially abrupt increase in size. We discuss various factors which influence rapid tumor growth including intratumoral hemorrhage and cystic change of tumor. CASE REPORT A 68-years old female presented with su...

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the...

Glossopharyngeal (that is, cranial nerve IX) schwannomas are extremely rare nerve sheath tumors that frequently mimic the more common vestibular schwannoma in their clinical as well as radiographic presentation. Although rare in adults, this tumor has not been reported in a child. The authors report the case of a 10-year-old boy who presented with several months of unilateral hearing loss. He w...

TARGET POPULATION Adults diagnosed with vestibular schwannomas. QUESTION 1 What is the prognostic significance of Antoni A vs B histologic patterns in vestibular schwannomas? RECOMMENDATION No recommendations can be made due to a lack of adequate data. QUESTION 2 What is the prognostic significance of mitotic figures seen in vestibular schwannoma specimens? RECOMMENDATION No recommendat...
