A Case of Pheochromocytoma during Pregnancy Missed Diagnosis as Preeclampsia

Document Type : Original Article

Abstract

Background: Adrenal pheochromocytomas and extra-adrenal paragangliomas are rare tumors, with an incidence of 2-8 cases per million per year, often presenting with non-specific symptoms such as palpitations, headaches, and sweating.
Objective: This study aimed todiagnose a case of pheochromocytoma during pregnancy.
Material and methods: It is challenging due to the limitations of radiological imaging and the risks associated with invasive procedures. Biochemical testing for urinary and plasma metanephrines is essential.
Management: It requires a multidisciplinary approach. The primary treatment is surgical removal, but this poses risks during pregnancy, including preterm labor. Control of blood pressure is crucial before considering surgery. Alpha-adrenergic blockers like phenoxybenzamine are typically used in non-pregnant patients, but their use in pregnancy is limited due to potential risks. Beta-blockers and labetalol are not recommended as standalone treatments. Conclusion: In this case, the plan was to manage blood pressure with calcium channel blockers, with surgical treatment deferred until after delivery.
