Multiple brain tumours with von Recklinghausen's disease.

Over the past 10 years we have experienced 33 cases of von Recklinghausen's disease, among whom 5 were cases of multiple (3 or more) brain tumours. In the past we have extirpated multiple tumours in a one-stage operation, but the results were poor. Recently, we have done multi-stage operation in two cases thought to require surgical treatment and have obtained satisfactory results. We have discussed the autopsy results of our own case of multiple neurinomas and meningiomas and have reviewed the 44 reported cases of von Recklinghausen's disease in whom the presence of three or more brain tumours had been confirmed at surgery or autopsy.
