Appearance of the right foot. The patient's toes were pale on admission (a), and enhanced computed tomography showed contrast delay in the lower extremities (b). This condition progressed to gangrene by hospital day 18 (c).

Lower extremity pulses in the dorsal artery of his right foot were absent, and the toes of his right foot were blue (Fig. 1a). Enhanced CT also showed contrast delay in the lower extremities (Fig. 1b), especially distal to the right ankle joint. HD 8 also detected the LV thrombus, but it could not be found on HD 18. His respiratory condition improved, and oxygen treatment was stopped; however, the toes of his right foot progressed to gangrene (Fig. 1c), and he was transferred to the Department of Orthopedics at another hospital for amputation of the foot.
Echocardiographic and chest and imaging on admission. Thrombus was detected in the left ventricle by transthoracic echocardiography (arrow) (a). Chest X-ray on admission showed bilateral consolidations and cardiomegaly (b). Chest computed tomography (CT) showed bilateral consolidations and ground-glass opacities (c). Enhanced CT showed filling defects in the pulmonary arteries (d).

A low-echoic nodule of 12 mm in size was detected in the LV apex (Fig. 2a). Chest X-ray showed bilateral consolidations and cardiomegaly (Fig. 2b). Chest computed tomography showed consolidations and ground-glass opacities distributed in the bilateral lung fields (Fig. 2c). Enhanced computed tomography (CT) detected filling defects in the pulmonary arteries (Fig. 2d), and a vascular echogram of the lower extremities showed low-echoic thrombus in the right femoral vein, great saphenous vein, bilateral popliteal vein, and the cnemial veins (posterior tibial vein, peroneal vein, and soleus muscle vein).
