Life-Threatening Cardiac Manifestations of Pheochromocytoma

Abstract EN

Pheochromocytoma is a catecholamine-secreting tumor of the adrenal glands, usually with benign manifestations, whose typical clinical presentation includes the triad of headache, palpitations and diaphoresis.

However, a wide range of signs and symptoms may be present.

In the cardiovascular system, the most common signs are labile hypertension and sinus tachycardia.

Systolic heart failure and ST-segment deviations mimicking myocardial infarction have also been reported, as well as QT interval prolongation and, rarely, ventricular tachycardia.

We describe a challenging diagnosis of pheochromocytoma with many cardiovascular manifestations, which could have been missed due to the absence of typical symptoms.
