Testicular non-seminomatous germ cell tumors (NSGCT) and brain metastases: About a rare location of the posterior fossa

Testicular cancer, which accounts for only 1% of all male cancers, is the most common cancer in men aged from 15 to 35 years. Germ cell tumors account for 90%–95% of cases. Of these germ-tumors, the non-seminomatous form (NSGCT) is the most common metastasis affecting the lungs, liver, central nervous system and bone in order of frequency. The frequency of brain metastases is very low, not exceeding 1.2%. The treatment is based on excision and chemotherapy and the prognosis remains moderately good with a 5-year survival rate of around 96%.
