 note = {We present a case of the extremely rare occurrence of a second germ cell tumor at different site and with different histological types 5 years after total resection of a pineal mature teratoma on September 25, 1998 a 8-year-old girl was admitted to our hospital with headache and vomiting. Computed tomography (CT), magnetic resonance imaging (MRI) studies showed a heterogeneous intensity mass in the pineal lesion and hydrocephalus. The tumor was totally removed by an occipital transtentorial approach. Histologic investigation revealed a mature teratoma without germinomatous components. Five years and 7 months later, she readmitted. Contrast-enhanced MRI revealed a heterogeneously enhanced mass localized in the neurohypophysis extending to the suprasellar. The patient was received three cycles of combination chemotherapy consisting carboplatin and etoposide. After the first course of chemotherapy, MRI scans revealed no evidence of tumor.},
