case_images: Chest computed tomography (CT) images of the patient. Two days before admission, CT revealed a few infiltrates in the right middle lobe and left lower lobe, with a small amount of left pleural effusion (A,B). On day 2 after admission, CT revealed opacity in the right lower lobe's dorsal segment, consolidation, atelectasis of the left lower lobe, and left pleural effusion (C,D). On day 7 after admission, computed tomography pulmonary angiography (CTPA) at the lung windows (E) showed peripheral wedge-shaped density on the right side (blue arrow), representing pulmonary infarction. Sagittal reconstruction of CTPA showed filling defects (red arrows) in the right main pulmonary artery (F) and pulmonary branches (G), and the left inferior pulmonary artery (H), consistent with clots. One month after discharge, follow-up CTPA showed the formation of a cavity (green arrow) (I) and the disappearance of filling defects (J-L).

case_images: C-reactive protein (CRP) level (66.8 mg/L, normal <6 mg/L), normal serum cardiac enzymes, and normal arterial blood gas analysis. Chest computed tomography (CT) revealed infiltrates in the right middle and left lower lobes, with a small amount of left pleural effusion (Figures 2A,B). Repeat chest CT showed an opacity on the right lower lobe's dorsal side, consolidation and atelectasis of the left lower lobe, and moderate left pleural effusion (Figures 2C,D). Emergency computed tomography pulmonary angiography (CTPA) revealed peripheral wedge-shaped densities in the lower lobes of both lungs, representing pulmonary infarctions and filling defects in the right main pulmonary artery, left inferior pulmonary artery, and their branches, which were consistent with the presence of clots (Figures 2E-H). Repeated CTPA showed resolution of consolidations, thrombosis, pleural effusion, and cavity formation in the dorsal side of the right lower lobe at the 1-month follow-up (Figures 2J-L).
