Symmetric left ventricular hypertrophy or asymmetric septal hypertrophy associated with pheochromocytoma simulating hypertrophic obstructive cardiomyopathy have been rarely reported. In this report, we present a case with pheochromocytoma that had dynamic left ventricular outflow tract obstruction without asymmetric septal hypertrophy. A surface echo revealed resolution of the systolic anterior motion of the mitral valve and all Doppler evidence of left ventricular outflow tract obstruction following removal of the tumor. Dynamic left ventricular outflow tract obstruction seen in this patient was probably due to excessive secretion of cathecolamines by the tumor.
