Pregnancy in a case of Nelson's syndrome

A woman suffering from Cushing's disease from the age of 17 who had been treated consecutively with pituitary irradiation, bilateral partial adrenalectomy and o,p'-DDD (Mitotane, USP) presented the clinical picture of Nelson's syndrome (hypoadrenalism with secondary hypersecretion of ACTH and MSH) at the age of 32. Under substitution therapy with corticoids she became pregnant for the first time at the age of 38. The course of the pregnancy was normal and at term she was delivered of a normal child by Cesarean section. The materno-fetal relationship, the increased risk of pituitary infarction during pregnancy and the possible teratogenic effect of chemotherapy in such cases are discussed.
