Abstract

We report I case of diabetes insipidus associated with suprasellar germinoma, obstructive hydrocephalus and both optic nerve atrophy. In this patient, symptoms of increased intracranial pressure was preceded by characteristic polyuria and polydipsia. The water restriction and pitressin test resulted in central originated diabetes insipidus. Computerized tomography in the brain revealed smooth marginated rounded mass density measuring 3.9 cm obliterating 3rd ventricle and extending to suprasellar region. On neurosurgical operation, egg sized tumor mass was noted in suprasellar area with complete obstruction of 3rd ventricle. The cytological and histopathological findings revealed malignant atypical teratoma(Ectopic pinealoma) which is extremely rare in pediatric age. The patient was received partial excision of tumor mass and ventriculo-peritoneal shunt. After operation, the patient was exhibited progressive renal failure and discharged against doctors order without improvement. We also briefly reviewed with related literatures.
