Lymphocytic adenohypophysitis causing pituitary mass.
Lymphocytic infiltration of the anterior pituitary is a rare complication of pregnancy, which has been reported in 18 cases. Symptoms begin in the last trimester or soon after delivery. Radiologically, an expanding mass in the sella may result in suprasellar extension. We studied a case in which there was CT evidence of a pituitary mass 2 weeks postpartum, and biopsy confirmed the diagnosis.
