title: Pathological laughter as a presenting symptom of acoustic schwannoma: report of two cases.
abstract: Two cases of acoustic schwannoma in a 48-year-old woman and 18-year-old male are reported. Both patients presented with an extremely unusual symptom of pathological laughter as a principal presenting symptom. Complete resection of the tumour via a retrosigmoid route resulted in an immediate resolution of pathological laughter.
