[Extracranial metastases from medulloblastoma: report of four cases (author's transl)]

Abstract

Four cases of bone and pulmonary metastases of medulloblastoma histologically diagnosed and with an exhaustive clinical-radiological and scintigraphic documentation, are described. In three patients, one of which non operated, the metastases of the osteolytic and osteoblastic type affected diffusely the skeleton; in the fourth patient the bone lesions were associated with a single pulmonary metastasis. The modality of metastatic spread and the clinical course of the illness in the diagnostic and therapeutic aspects are discussed.
