title: Bladder pheochromocytoma in pregnancy without hypertension. A case report.
abstract: A 33-year-old nullipara presented at 20 weeks' gestation with episodes of nonsustained ventricular tachycardia, which were controlled with amiodarone. No hypertension was recorded except once after an attack of ventricular tachycardia. Pheochromocytoma was suspected when repeat 24-hour urine catecholamine levels were markedly elevated. Neither computed tomography nor postpartum metaiodobenzylguanidine scan could locate the tumor. Finally it was identified in the bladder by ultrasound after selective venous sampling localized it to the pelvis. It was excised four months postpartum.
