Pheochromocytoma in pregnancy: a case report.

A 25-year-old woman, primigravida, developed the clinical picture of sporadic hypertension (blood pressure 120-230/70-130 mmHg), palpitations, flushing and sweating attacks at 34 weeks' gestation. A 24-hour urine collection revealed catechol levels consistent with a diagnosis of pheochromocytoma. The ultrasound and MRI showed a well-defined, rounded soft-tissue mass at the left suprarenal region. The hypertension was controlled with alpha-blockade. Antepartum fetal testing was normal. The patient underwent cesarean section at 38+1 weeks' gestation and delivered a 2,930-grams male with Apgar scores of 9 and 10 at one and five minutes. Left adrenalectomy was performed two weeks later. The pathologic diagnosis was pheochromocytoma.
