Abstract

Antepartum pituitary infarction occurs only in insulindependent diabetic patients. It is manifested by severe headache, followed by decreasing insulin requirements. Delivery is frequently premature, with high fetal wastage and increased maternal mortality. During the puerperium, the first manifestation of pituitary deficiency, other than a lower insulin requirement than would be expected, is failure to lactate. Subsequent evaluation of pituitary function reveals variable deficiencies with loss of growth hormone and gonadotropins being most frequent. This case is the eighth report of this entity, and it represents the first patient to survive a pituitary infarction prior to the third trimester of pregnancy. Recognition of this syndrome is critical in order to ensure that the mother's health and the viability of the offspring be preserved.
