case_images: Cardiac mass histology: Hematoxylin-eosin stains of endomyocardial biopsy
  showing fibrinopurulent exudate on the endocardial surface (left). The
  photograph on the right shows a higher magnification of the exudate,
  including fibrin and inflammatory cells with necrotic debris.

case_images: Pathological examination of the cardiac tissue revealed fibrinopurulent exudate, granulation tissue (Figure 1), and rare gram positive coccoidal forms worrisome for infectious endocarditis.

case_images: Chest CT angiography showed 2 large right pulmonary artery pseudoaneurysms (PAPs) and new pulmonary emboli (Figure 2A, C). Two weeks after cyclophosphamide initiation, an echocardiogram showed minimal evidence of RV mass, and chest CT angiography revealed no PAPs or emboli (Figure 2B).
case_images: Pulmonary artery histology: Hematoxylin-eosin stains of the pulmonary artery
  wall showing a lymphocytic inflammatory infiltrate in the arterial wall,
  marked dilatation of the lumen, intraluminal thrombosis, multifocal intimal
  fibrinoid necrosis, and elastic layer fragmentation (left). The photograph
  on the right shows a higher magnification of the lymphocytic inflammatory
  infiltrate in the pulmonary arterial wall and elastic fragmentation.
