Cardiac manifestation of acute lymphoblastic leukemia

Here, we report on a 38-year-old man with unclear right heart failure. Imaging with cardiacMRI and combined PET/CTwith ¹⁸F-FDG revealed a hypermetabolic mass extending from the right ventricle to the atrium. In addition, intense glucose utilization throughout the bone marrow was noted. Biopsies of both bone marrow and cardiac mass were performed and revealed precursor B-cell acute lymphoblastic leukemia with gross leukemic infiltration of the myopericardium, a rare manifestation of acute lymphoblastic leukemia at initial diagnosis.
