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.
