Trigeminal Ophthalmic Branch Schwannoma: Case Report and Literature Review
Arq. bras. neurocir; 40 (1), 2021
Publication year: 2021
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.
