Abstract

Schwannomas are the fourth most common primary neoplasms affecting the brain and cranial nerves. Central lesions commonly arise from sensory nerve roots, and a common intracranial site is the vestibular branch of the 8th nerve (>85%). We present the case report of a patient who has a schwannoma extending from the pterygopalatine fossa to the orbit, complaining about facial pain in the trajectory of the trigeminal ophthalmic branch. Schwannomas represent 1 to 2% of all neoplasms of the orbit, and trigeminal schwannomas are extremely rare, accounting for less than 0.5% of all intracranial tumors.

Resumo

Schwannomas são a quarta neoplasia primária mais comum que afeta o cérebro e os nervos cranianos. As lesões centrais comumente surgem de raízes nervosas sensitivas, e um sítio intracraniano comum é o ramo vestibular do oitavo nervo (mais de 85% dos casos). Apresentamos o relato de caso de um paciente portador de schwannoma que se estende da fossa pterigopalatina até a órbita, com queixa de dor facial no trajeto do ramo oftálmico do nervo trigêmeo. Schwannomas representam 1–2% de todas as neoplasias da órbita e schwannomas trigeminais são extremamente raros, respondendo por menos de 0,5% de todos os tumores intracranianos.
