[Lymphocytic adenohypophysitis. Apropos of a new case]

A new case of lymphocytic adenohypophysitis in a five months pregnant woman is related. The sudden appearance of visual symptoms required a surgical procedure. MRI does not enable a precise preoperative diagnosis. Three months after delivery clinical data as hormonal functions returned to normal and also the CT Scan aspect. Eighteen months later the patient remains totally normal. In our case we don't find any argument in favor of an autoimmune disease.
