A Case of Pheochromocytoma during Pregnancy Missed Diagnosis as Preeclampsia

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 to diagnose 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. Alphaadrenergic 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
