[A case of acoustic neurinoma in a girl aged 13]

A 13-year-old girl with large richly vascularized acoustic neurinoma is reported. The family history and clinical evidence failed to suggest neurofibromatosis in the family. The clinical syndrome included paroxysmal headaches, vertigo, loss of consciousness and left ear hearing loss. The application of Nd-YAG laser during the operation reduced bleeding and enabled radical removal of the tumour.
