Pheochromocytoma and Paraganglioma in Pregnancy: a New Era.

PURPOSE OF REVIEW: Pheochromocytoma and paraganglioma (PPGL) in pregnancy is a rare entity and management of these patients is fraught with uncertainty. Our objective is to review current literature and discuss diagnosis and management of these patients. RECENT FINDINGS: Outcomes of PPGL in pregnancy have improved in recent years. The greatest risk for adverse maternal and fetal outcomes is the diagnosis of PPGL after delivery. Alpha- and beta-adrenergic blockade is well tolerated and is associated with less adverse outcomes. Antepartum surgery is not associated with improved maternal or fetal outcomes. Biochemical testing and cross-sectional imaging should be performed prior to conception for patients with a known germline variant associated with PPGL. CONCLUSIONS: Medical therapy should be initiated when PPGL is diagnosed in pregnancy. Antepartum surgery should be reserved for special circumstances. Case detection testing in high-risk patients can identify PPGL before pregnancy.
