Summary
Diagnosing pheochromocytoma during pregnancy is critical for maternal and fetal health, often missed due to vague symptoms. Accurate diagnosis relies on free metanephrine levels, with MRI preferred for imaging.
Area of Science:
- Obstetrics and Gynecology
- Endocrinology
- Surgical Oncology
Background:
- Pheochromocytoma in pregnancy is a rare but life-threatening condition.
- Delayed diagnosis jeopardizes both maternal and fetal well-being.
- Symptoms often mimic common pregnancy complications, leading to diagnostic challenges.
Purpose of the Study:
- To highlight the diagnostic and management strategies for pheochromocytoma during pregnancy.
- To emphasize the importance of timely diagnosis and intervention.
- To provide guidance on optimal surgical timing and delivery methods.
Main Methods:
- Review of diagnostic accuracy of plasma or urinary free metanephrines.
- Comparison of MRI and ultrasonography for tumor localization.
- Analysis of optimal timing for surgical adrenalectomy.
- Evaluation of delivery methods in affected pregnancies.
Main Results:
- Plasma or urinary free metanephrines offer the highest diagnostic accuracy.
- MRI is the preferred imaging modality over ultrasonography.
- Surgical removal is recommended before 24 weeks of gestation or post-delivery.
- Laparoscopic adrenalectomy requires medical pretreatment.
Conclusions:
- Early and accurate diagnosis of gestational pheochromocytoma is paramount.
- Multidisciplinary management involving endocrinologists, surgeons, and obstetricians is essential.
- Tailored surgical and delivery strategies improve maternal and fetal outcomes.
