Acute Development of Biventricular Masses in a Patient with Chronic Lymphocytic Leukemia

Tony Chen, MD, Sina Jame, MD, Yogendra Kanthi, MD

A 51-year-old African American male was admitted for initiation of bendamustine for the treatment of chronic lymphocytic leukemia (CLL). His had a complicated hospital course characterized by new onset and difficult to control atrial fibrillation with rapid ventricular rate, intracranial hemorrhage in the setting of thrombocytopenia and neutropenic fever with positive blood cultures. An echocardiogram was obtained. His prior transthoracic echocardiogram had demonstrated a dilated left atrium and left ventricle with an otherwise normal LV systolic function. The repeat transthoracic echocardiogram one month later revealed the presence of two wide-based, nonmobile masses, one of which was attached to the inferior and inferoseptal wall of the left ventricle, while the other was located in the right ventricular outflow tract below the pulmonic valve (Figure 1). Subsequent cardiac magnetic resonance imaging (CMR) identified an additional third mass at the right ventricular anterior wall. (Figure 2).
