[Extracerebral metastases from cerebral glioblastoma]

A patient with glioblastoma multiforme in the right cerebral hemisphere had extracranial metastases, probably mediated via a ventriculoperitoneal shunt. Extracranial spread of malignant tumours of the central nervous system is very rare. We point out the possibility of metastases in patients who have undergone craniotomy or who have a systemic shunt. We discuss other possible ways of spreading, prophylactic measures, and the various modalities of treatment for these metastases.
