Core Tip
Core Tip: This case highlights an exceptionally atypical presentation of pheochromocytoma dominated by refractory vomiting and complicated by acute catecholamine-induced cardiomyopathy with heart failure (left ventricular ejection fraction 30%). Initial misdiagnosis as coronary artery disease occurred due to mild stenosis on angiography. The critical diagnostic clue emerged with dramatic paroxysmal hypertension (fluctuating from 202/129 mmHg to 97/51 mmHg). This report underscores that pheochromocytoma must be considered in patients with unexplained treatment-resistant vomiting coexisting with acute heart failure, particularly when labile hypertension appears. Timely biochemical screening (catecholamine metabolites) and adrenal imaging are essential to prevent life-threatening delays.
