We report a case of pheochromocytoma in which left ventricular configuration mimicking hypertrophic obstructive cardiomyopathy (HOCM) disappeared after operation. A twelve-year-old boy was hospitalized for headache and palpitation accompanied hypertension. A 24-hour urine collection showed elevated cathecolamines and abnormal ultrasonographic examination and computed tomography revealed a right adrenal mass. The right adrenal pheochromocytoma was diagnosed and it was removed without complication.
Echocaridiograms were performed in this case before and after operation. Before operation systolic anterior movement (SAM) and asymmetric septal hypertrophy (AHS) were demonstrated. Post operatively (4 months) ASH disappeared and 8 months after surgical removal of the tumor SAM disappeared. So we thought excessive catecholamines probably effected ventricular wall thickening in this case.
