Partial Resection of a Huge Left Ventricle Cardiac Fibroma in an Asymptomatic Child.

An asymptomatic, 9-year-old boy was referred to our institution for a left ventricular cardiac mass incidentally discovered during a medical examination. The patient was asymptomatic and physical examination was unremarkable. Chest radiography showed an abnormal heart shadow in the left ventricle field. Echocardiography revealed an echo-bright mass attached to the left ventricle free wall with mitral obstruction or compromise to the flow. Computed tomography was performed, from which a large, well-defined, and space-occupying lesion mass could be seen. Positron emission tomography confirmed that the localized glucose metabolism of the left ventricle free wall was reduced due to a large, homogeneous, well-delimited mass.
