title: A suprasellar atypical teratoma presenting as an intrasellar mass: a case report.
abstract: Intracranial atypical teratomas are midline brain tumors with both germinomatous and teratomatous elements. When they occur in the suprasellar region, they usually present with a classic triad of visual disturbances, diabetes insipidus, and hypopituitarism. We report the case of a suprasellar atypical teratoma that presented as an intrasellar lesion and caused secondary amenorrhea in a 15-year-old girl.
