Pregnancy induced Cushing's syndrome and primary aldosteronism: a case report

First manifestation of Cushing's syndrome during pregnancy is rare. The diagnosis of both Cushing's and primary aldosteronism within a pregnancy has not been previously documented. Diagnosis is especially challenging due to the normal physiological changes that occur during pregnancy. Consequently, many tests that are normally used for diagnosis are not reliable. Tumor based etiologies can be surgically removed. Etiologies that are not tumor based are challenging to treat during pregnancy.

A 25 year old G1P0 was admitted in the 22 ^5/7 week of pregnancy with elevated blood pressure (200/100 mm Hg), acne, moon facies, abdominal striae and hirsutism. With five antihypertensive medications her blood pressure remained 190/100 mm Hg. The patient was admitted to the ICU for intravenous medications and monitoring. She was diagnosed with Cushing's syndrome and primary aldosteronism. In spite of therapy with spironolactone and metyrapone she developed preeclampsia and was delivered in the 26 ^0/7 week of pregnancy. At her follow up visit eight weeks postpartum she had blood pressure within normal limits, no clinical signs or symptoms, and all medications had been discontinued.

Early diagnosis of pregnancy induced Cushing's syndrome and primary aldosteronism requires an interdisciplinary approach. Late detection has been associated with increased perinatal morbidity and mortality including but not limited to placental abruption and intrauterine demise. Collaboration is essential in the optimization of maternal and fetal outcomes.
