[Germinal tumor metastases. Case report]

Germinoma is the most frequent type of intracranial germ-cell tumor initial presentation is usually acute intracranial hypertension. MRI investigations are non-specific. Most of the time, only stereotactic surgery is performed before treatment. Metastases are rare but germ cells can disseminate both by infiltration and via ventricular and subarachnoid pathways. Abdominal and pelvic metastases occur in 10 p. 100 of patients who have received ventriculosomatic shunting. Since germinoma is well known to be a very radiosensitive tumor, patients are usually given radiation therapy. Chemotherapy seems to be an interesting alternative treatment.
