Right Atrial Cardiac Hemangioma

We present a case of a 76-year-old man with de novo right heart failure. Echocardiography initially detected a mass near to the posterior area of the right atrium. Despite a comprehensive multimodality imaging assessment, the exact location of the mass remained unclear. Positron emission tomography scan revealed comparable hypermetabolic activity to that of the bloodstream, suggestive of a vascular tumor. Surgical resection via right anterior mini-thoracotomy confirmed an intracardiac mass that was ultimately diagnosed as a capillary hemangioma. This case underscores the challenges in the era of advanced cardiac imaging modalities in precisely localizing and characterizing masses, particularly rare entities such as cardiac hemangiomas.
