Primary cardiac pheochromocytomas (PCP) are extremely rare. To date, less than 50 cases have been reported worldwide. In this report we present the case of an intrapericardial tumor in a middle aged woman, that was finally diagnosed as a primary pheochromocytoma, of which the main sign was severe hypertension (sHTN). Diagnostic imaging studies confirmed the presence of an intrapericardial tumor as the only finding, and biochemical assessment of urinary catecholamines and their metabolites further confirmed the diagnosis. The tumor was surgically resected without complications, using conventional on-pump cardiac surgery with cardiac arrest and cardioplegia. At follow-up seven months post surgery, the patient remains asymptomatic and normotensive.
