title: Extra-adrenal pheochromocytoma in pregnancy: ultrasonography and magnetic resonance imaging findings.
abstract: The authors describe a 24-year-old woman with extra-adrenal pheochromocytoma during pregnancy. Initial ultrasonography (US) at 27 weeks gestational age failed to show the pheochromocytoma, which was subsequently found by US at 35 weeks gestational age. Magnetic resonance imaging (MRI) provided diagnostic confirmation, as well as important information used by the obstetrician and the surgeon in operative planning.
