Multiple Intracranial Schwannomas: Case Report

Abstract

SUMMARY -Schwannomas are benign encapsulated tumors arising from the sheaths of peripheral nerves. Th ey present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple schwannomas in non-neurofi bromatosis type 2 patients are extremely rare. We report a case of a 60-year-old female patient, without any family history of neurofi bromatosis or schwannomatosis, presented with trigeminal neuralgia and progressive facial nerve palsy. Magnetic resonance imaging revealed the presence of acoustic schwannoma involving facial nerve and trigeminal schwannoma of the cisternal part of the nerve involving gasserian ganglion (Meckel's cave). After gamma knife radiosurgery, trigeminal neuralgia was relieved completely with improvement of facial nerve palsy.
