Pheochromocytomas and paragangliomas during pregnancy: A case report and review of the literature

Pheochromocytoma is a rare, potentially lethal tumor that can be revealed by pregnancy, often mimicking a clinical picture of pre-eclampsia. We report the case of a pheochromocytoma that occurred in the 1st trimester, presenting with episodes of arterial hypertension (AHT). Treatment consisted of preoperative medical preparation followed by surgery. The maternal and fetal outcome was favorable. The occurrence of pheochromocytoma during pregnancy poses a problem in both diagnosis and blood pressure control. The therapeutic strategy depends on the gestational age, the maternal-fetal outcome (retention), and the response to medical treatment.
