Severe Klebsiella pneumoniae pneumonia complicated by acute intra-abdominal multiple arterial thrombosis and bacterial embolism: A case report

Figure 1 Physical examination: Skin scratches on both forearms and hands with occasional skin ulcerations.

Figure 2 Chest computed tomography imaging examinations. A: Multiple patchy, nodular, and flocculent high-density shadows in both lungs, with blurred edges and small voids in some lesions; B: The bilateral lung lesions increased, and the solid parts around some nodules increased, with reverse halo and trophovascular signs; C: The bilateral lung lesions were significantly absorbed and reduced compared with previous imaging.

Figure 3 Abdominal aortic computed tomography angiography imaging examinations. A: The proximal segment of the celiac trunk and superior mesenteric artery were embolized (as indicated by the red arrow), and the distal branch appeared small. The hepatic parenchyma around the gallbladder was enhanced in the arterial stage, with uneven local perfusion and a few calcified plaques in the abdominal aorta; B: Reperfusion of the proper hepatic artery, partial infarction of the spleen and cystic changes, blocked initial common pathway of the celiac trunk and superior mesenteric artery, but the embolization improved (as indicated by the red arrow), and obvious local stenosis.
