Metastasizing neuroectodermal tumour.

This report describes a medulloblastoma with extracranial metastases in a 24-year-old man. Postoperatively, 60Co irradiation was given and clinical recovery was good. Cervical lymph node metastases developed 2.5 years later. The patient received cytostatic treatment and a second course of radiation therapy with 60Co and lived for 6 years after the onset of symptoms, finally dying with signs of bronchopneumonia. The possible routes of spread are discussed.
