Primary aldosteronism with aldosterone-producing adrenal adenoma in a pregnant woman

A 30-year-old pregnant woman complained of muscle weakness at 29 weeks' ges tation. She was hypertensive with severe hypokalemia. Lower plasma renin ac tivity and higher aldosterone level than the normal values in pregnancy sug gested primary aldosteronism. A cesarean delivery was performed at 31 weeks ' gestation because of pulmonary congestion. The neonatal course was uncomp licated. The laparoscopic adrenalectomy for a 2.0-cm right adrenal adenoma resulted in normalizing of her blood pressure and serum potassium level. Al though primary aldosteronism is rare, especially during pregnancy, it shoul d be always considered as one of etiologies of hypertension in pregnancy.
