Curative resection of an aldosteronoma causing primary aldosteronism in the second trimester of pregnancy.

Primary aldosteronism is the most common etiology of secondary hypertension with an estimated prevalence of 5-10% in the hypertensive population. It is important to recognize the subtypes of primary aldosteronism given that certain forms can be treated surgically. Hypertension in pregnancy is associated with significantly higher maternal and fetal complications. Data regarding the treatment of primary aldosteronism in pregnancy are limited. Adrenalectomy can be considered during the second trimester of pregnancy if medical therapy fails to adequately control hypertension from primary aldosteronism.
