Right Ventricular Lipoma Arising from the Anterior Papillary Muscle: A Case Report

We report a rare case of right ventricular lipoma arising from the anterior papillary muscle in a 62 year-old man. Transthoracic echocardiography showed a homogeneous mass in the right ventricle attached to the anterior papillary muscle. Computed tomography showed features consistent with intracardiac lipoma, which was confirmed by histology.
