Abstract:
A 26-year-old male presented with a trigeminal neurinoma manifesting as pathological laughter. After resection of the large tumor, the symptom disappeared completely. Pathological laughter sometimes precedes other manifestations of tumors around the brainstem and may be a useful localizing sign.
