Incidental Finding of Right Atrial Mass in a Patient With Hodgkin Lymphoma: Utilization of Multimodal Cardiac Imaging in Diagnosis

Right atrial masses can be found incidentally on imaging studies, which could represent cardiac or non-cardiac tumors, vegetations, or thrombi. Catheter-related right atrial thrombosis is an uncommon and underdiagnosed condition, but has been associated with significant mortality risk. Herein, we present a case of a 56-year-old man with Hodgkin lymphoma who was found to have a right atrial mass on routine transthoracic echocardiogram. The diagnosis of right atrial thrombus was made by using transesophageal echocardiogram and cardiac magnetic resonance imaging. He was managed with intravenous heparin and was being evaluated for possible thrombectomy when he died from complications of septic shock.
