Pheochromocytoma is known from a wide range of clinical manifestations and can mimic other disorders which can lead to delay in diagnosis. We report a case of a young female presenting with chest pain, electrocardiographic changes, and episodes of ventricular tachycardia, finally diagnosed with this catecholamine-producing tumor. <Learning objective: Pheochromocytoma is a rare catecholamine-producing tumor that can pose a diagnostic challenge due to its multiple manifestations mimicking various conditions, including cardiovascular disorders. Despite its infrequent occurrence, pheochromocytoma should be considered as a possible cause of life-threatening cardiac arrhythmias and electrocardiographic changes in patients with diagnostic difficulties and primarily suspected of having cardiovascular disease. Furthermore, the method of treatment is entirely different.>.
