Abstract

Trigeminal schwannoma is an uncommon intracranial tumor and constitutes less than 0.08-8% of all intracranial schwannoma. Trigeminal shchwannoma is even rarer in childhood and only 11 cases of trigeminal schwannoma under the age of 14 have been reported including our case. We experienced a case of trigeminal schwannoma in a 9 year-old girl without the stigmata of neurofibromatosis. She presented with a 2 week-history of right abducens nerve palsy. Magnetic resonance image demonstrated a dumbbell-shaped tumor extending into right middle and posterior fossas with a size of $60{\times}45{\times}35mm$. The tumor was successfully removed by right transzygomatic subtemporal extradural approach. Pathologic examination of the mass revealed typical features of schwannoma.
