Permanent (CSF-drainages for treatment of hydrocephalus in posterior fossa tumors
have been used in the last few years, increasingly. The rare incidence of extracranial
metastases and it's higher frequency in the same period of time has been remarkable.
An additional case of metastasis via ventriculoperitoneal shunt is presented. Such
deleterious complications of malignant CNS-tumors should be avoided, as progressively
improving results with combined radio-chemotherapy have established a more encouraging
prognosis.
