Answer f. Pheochromocytoma mimics many conditions and may present during manipulation of the bladder (Foley catheter placement) or during an unrelated surgical procedure. Unexplained sustained hypertension should prompt a widening of the diagnosis and aggressive treatment. A study of modern perioperative complications associated with pheochromocytoma noted that in patients who died, only one anti-hypertensive agent (without alpha-blockade) was used, and four of five deaths were associated with pregnancy (hypertension possibly confused for pre-eclampsia) or hysterectomy (Hariskov J Anaesthesiol Clin Pharmacol (2013) 29(1): 41–46).
