title: Intracranial lesion resembling giant lymph node hyperplasia.
abstract: A 30-year-old woman, who, since the age of 20, had epileptic seizures, was hospitalized in 1972 because of frontal headaches, nausea, and vomiting. Clinical examination revealed a right cerebellar syndrome; gamma-encephalogram showed a focus of subtentorial hyperactivity; iodoventriculography showed a deformation of the aqueduct. At surgery, a posterior fossa tumor implanted on the dura mater and tentorium of the right cerebellar fossa was enucleated. The histologic features were those of giant lymph node hyperplasia. Postoperative craniospinal radiotherapy was administered. Ten years later the patient was in good health and neurogically normal.
