- Abstract
The authors report on 3-year-old-girl with neuroblastoma complicated by severe hypertension and cardiac failure. She had cardiomegaly and pleural and pericardial effusions. Echocardiogram showed left ventricular hypertrophy and decrease of the left ventricular ejection fraction to 0.36 (normal > .40). Abdominal computed tomographic scan indicated a 7 x 7-cm tumor in the left suprarenal area. There was a marked increase in catecholamines and metabolites in her body fluids. After hypertension was controlled with doxazosin (a long-acting alpha 1 adrenergic blocker), her cardiac function gradually improved. A tumor was surgically removed and diagnosed as a poorly differentiated ganglioneuroblastoma. Preoperative differentiation between neuroblastoma and pheochromocytoma was not possible on the basis of catecholamine analysis or imaging studies including computed tomography scan and magnetic resonance imaging. It is important to control hypertension quickly in the patients with catecholamine-induced cardiomyopathy to facilitate surgical intervention for diagnosis and treatment.
