Synchronous hypothalamic and pineal germinomas. Synchronous hypothalamic and pineal germinomas. T1W MRI shows T1 isointense pineal and hypothalamic masses. The hypothalamic mass extends to involve the infundibulum and pituitary gland. The posterior pituitary high signal is absent—the patient had central diabetes insipidus. The pineal mass compressed the aqueduct and posterior third ventricle, without hydrocephalus. Gadolinium-enhanced images of the brain and spine showed avid enhancement of both lesions but no leptomeningeal dissemination.
