title: Intracranial germinoma with syncytiotrophoblastic giant cells in the cerebellopontine angle--case report.
abstract: A 23-year-old man presented with a 3-week history of left hearing disturbance and left facial nerve paresis. T1-weighted magnetic resonance (MR) imaging showed an iso-intense mass in the left cerebellopontine angle (CPA), with homogeneous enhancement with gadolinium-diethylenetriaminepenta-acetic acid. T2-weighted MR imaging showed the mass as heterogeneously iso- to hyperintense. Gross total removal of the tumor was achieved. Histological examination revealed that the tumor was a germinoma with syncytiotrophoblastic giant cells. Whole central nervous system irradiation with cisplatin-etoposide chemotherapy was performed postoperatively. He has been in good condition with no sign of recurrence for 7 years. Intracranial germ cell tumors in the CPA are very rare. Total surgical removal followed by irradiation and chemotherapy will provide a good outcome.
