Abstract
Lymphocytic hypophysitis (LyH) is a rare disorder characterized by lymphocytic infiltration of the pituitary gland invariably resulting in pituitary hormone deficiency. LyH is usually diagnosed at surgery in young women during late pregnancy or at the post partum period. The effect of a subsequent pregnancy on the course of the disease is not known. We describe the first case of pregnancy and delivery in a woman with established LyH and partial hypopituitarism.
