title: Pheochromocytoma with negative urinalysis in pregnancy.
abstract: We present a rare case of adrenal pheochromocytoma in pregnancy, with serial 24-h urine specimen collections showing normal concentrations of catecholamine metabolites. The diagnosis was based on clinical presentation, abdominal ultrasound, and magnetic resonance imaging, and was confirmed on post-operative pathohistological examination. Clinical suspicion of pheochromocytoma in pregnancy should be sufficient to implement adequate therapeutic measures, regardless of urine catecholamine concentrations.
