The authors report a case of pheochromocytoma in which the echocardiographic features suggested obstructive hypertrophic cardiomyopathy. The angiographic study and the computed tomography showed the tumor and its arterial supply. One month after resection of the tumor the echocardiographic features showed a tendency to normalization. The preoperative echocardiographic aspect was probably due to excessive production of catecholamines by the tumor.
