Rapid reversal of dilated cardiomyopathy following removal of neuroblastoma

Abstract Reported is a child with dilated cardiomyopathy, in whom medical therapy resulted in a mild improvement of cardiac function. Metabolic studies suggested the presence of a catecholamine-secreting tumour; and an adrenal neuroblastoma was identified and surgically removed. Following surgery, there was progressive and complete normalization of cardiac function. Although very rare, neurogenic tumours may be involved in the development of a dilated cardiomyopathy in the infant and child.
