Cardiac fibroma in an infant: magnetic resonance imaging characteristics.

Primary cardiac neoplisms are uncommon, with a reported prevalence of 0.0017-0.28% of autopsies (1). Approximately 15% of these are benign tumors, of which the most common is myxoma. Cardiac fibroma is a rare benign tumor that primarily occurs in infants and children. Imaging modalities used for diagnosis of cardiac masses include echocardiography, computed tomography, and magnetic resonance imaging (MRI). MRI can depict the anatomic extent of the tumor and the pattern of contrast enhancement. In addition, cine MRI can demonstrate functional pathology of the heart and circulation dynamics. The current report describes an infant with right ventricular fibroma on whom MRI was performed to demonstrate the extent of the tumor and to suggest a specific diagnosis.
