title: Pheochromocytoma in Pregnancy: When is Operative Intervention Indicated?
abstract: Pheochromocytoma is rare in pregnancy, with an estimated incidence of 0.007%. Diagnosis is difficult owing to the variety of presentations and nonspecific symptoms. Nevertheless, unsuspected disease accounts for a significant proportion of morbidity and mortality. Currently, there appears to be no consensus on management with regard to the need for and timing of medical vs. surgical management. In this case report, we describe two patients who underwent different modes of treatment based on careful consideration of disease-related and nondisease-related factors. We emphasise that good outcomes can be achieved through individualized management within the context of a multidisciplinary team, involving close collaboration among physicians, surgeons, obstetricians, and anesthetists. We also illustrate the importance of genetic testing in all patients with pheochromocytoma in pregnancy, especially with the emergence of new predisposing genes (succinate dehydrogenase B and D) and the recognition that germline mutations in these and more established genes (VHL and RET) account for over a quarter of all apparently sporadic cases.
