Panhipopituitarismo y diabetes insípida secundarios a hipofisitis linfocitaria en una paciente con trisomia 12p / Panhypopituitarism and diabetes insipidus secondary to a lymphocytic hypophysitis in one patient with trisomy 12p

ABSTRACT

Lymphocytic hypophysitis (LH) is an uncommon inflammatory disease of the hypophysis. It's female to male ratio of appearance is 9:1. Pregnant women are more affected during the third trimester of pregnancy or postpartum. Clinical and radiological presentation can simulate a hypophyseal adenoma. We report a nonpregnant 13 years old adolescent, with a trisomy 12p, with panhypopituitarism, diabetes insipidus and a selar tumor. It was necessary to differentiate between a germinoma and a LH. The latter was confirmed with the hypophyseal biopsy.
