[Extraneural medulloblastoma metastasis following non-operated medulloblastoma].
We present a case of a 3 8/12 years old boy with histologically proved medulloblastoma. Preoperatively a tumor of the parotid gland was diagnosed, exstirpated and interpreted as a metastasis of medulloblastoma. Therefore the opinion seems to be questionable, that extracranial metastases of medulloblastomas only occur after injury of the dura mater (operation, shunt).
