Ashwin Kumaria et al. Br J Neurosurg. 2022 Feb.

Abstract

We present the case of a 66 year old gentleman with trigeminal schwannoma whose only presenting feature was a single gelastic seizure. This is the first case report of pathological laughter in trigeminal schwannoma in the absence of other trigeminal, brainstem, cerebellar or other cranial nerve dysfunction.

Keywords: Trigeminal schwannoma; gelastic seizure; pathological laughter; skull base tumours.
