Papillary endothelial hyperplasia (PEH) is a benign process characterized by endothelial cell proliferation in a papillary pattern, usually occurring in reaction to traumatic vascular stasis or a thrombus. Commonly found in the soft tissues of the neck and extremities, intracardiac lesions in the left atrium, left ventricle, and coronary atherotomy specimens associated with trauma or thrombus have rarely been reported. A single prior report of a pure, isolated form of intracardiac PEH in the literature is noted. To the best of our knowledge, the imaging characteristics have not been described. We describe the dynamic magnetic resonance characteristics of a pure, isolated PEH occurring in the right ventricle.
