Supratentorial intracerebral schwannomas.

A case of frontotemporal intracerebral schwannoma in a 16-year-old girl with epilepsy and progressive hemiparesis of 3 years' duration is described. The histologic diagnosis and possible sites of origin are discussed. In addition, five previously reported cases of supratentorial intracerebral schwannoma are discussed. All of the patients reviewed presented with epilepsy early in life, and there was no association with neurofibromatosis.
