Suprasellar cystic germinoma.

We report on a germinoma in the suprasellar region, which had multiple large cystic components. A 13-year-old girl with disturbed visual acuity and growth retardation was admitted to our hospital for treatment of an intracranial tumor. The lesion was difficult to diagnose as a germinoma preoperatively, because of its radiographic characteristics. Histopathological examination revealed that the tumor was a germinoma. Surgery, chemotherapy with carboplatin and etoposide, and radiotherapy (30 Gy) were successful in inducing complete remission of the tumor. The patient's endocrine status remained normal, except for a low GH concentration and diabetes insipidus.
