Abstract:
Pheochromocytoma, a rare but potentially serious condition, poses challenges in timely identification, especially during pregnancy due to misconceptions about pregnancy-related hypertension causes. However, paroxysmal symptoms heighten diagnostic suspicion. The diagnosis relies on biochemical confirmation of catecholamine hypersecretion followed by imaging for tumor localization. When diagnosed at or after 24 weeks, alpha-adrenoceptor blockers are recommended during pregnancy to manage catecholamine excess, delaying tumor removal until viability or post-delivery. The rarity of this condition during pregnancy, coupled with diagnostic and management challenges, underscores its importance for obstetric professionals in addressing hypertensive control, delivery timing, and surgical intervention.
