case_images: (A,B) The chest CT angiography showed a filling defect in the left lower pulmonary artery and right ventricle. (C) Echocardiography revealed multiple mass echos in the right ventricle (4 x 3 mm, 13 x 5 mm, and 9 x 5 mm) on day 3. (D) Echocardiography revealed mass echos in the right ventricle (8 x 13 mm) on day 12.

case_images: Echocardiography (Figure 1C) revealed multiple mass echos in the right ventricle (4 x 3 mm, 13 x 5 mm, and 9 x 5 mm). CT angiography showed a filling defect in the left lower pulmonary artery and right ventricle (Figures 1A,B). Coagulation analysis revealed elevated D-dimer levels (10 mg/L; normal reference range, 0-0.55 mg/L) and fibrinogen (FIB) (6.683 g/L; normal reference values, 2-4 g/L). Echocardiography (Figure 1D) showed a right ventricular mass echo (8 mm x 13 mm).
case_images: Changes of FIB, D-dimer before and after application of thrombolytic drugs.
