RESUMO
Cardiac tumors are neoplasms arising from or located in the heart or the pericardium. Although rare, primary cardiac tumors in children require an accurate and timely diagnosis. Most pediatric primary cardiac tumors are benign (around 90%). Echocardiography is the first imaging modality used due to its availability, noninvasiveness, inexpensiveness, and absence of ionizing radiation. Computed tomography (CT) and magnetic resonance imaging (MRI) offer better soft tissue visualization as well as better visualization of extracardiac structures. A great advantage of MRI is the possibility of measuring cardiac function and blood flow, which can be important for obstructing cardiac tumors. In this article, we will offer a brief review of clinical, echocardiographic, CT, and MRI features of cardiac rhabdomyomas, fibromas, teratomas, and lipomas providing their differential diagnosis.
