FIG1
A computed tomography angiography (CTA) scan of the abdomen revealed an extensive thrombus in the splenic artery, with no signs of any malignancy (Figure 1).
Representative image of a CT scan of the abdomen showing a filling defect indicating persistent thrombus in the splenic artery, as well as visible infarction in the spleen.. (A) Area within the red circle indicates the location of the thrombus. (B) Green arrow indicates normal area of the spleen, which is hyperdense. Red arrow indicates the infarcted area of the spleen, which is hypodense.

FIG2
A computed tomography (CT) scan of the abdomen showed that the previous thrombus had increased in size to fill the entire splenic artery, as well as a low-density splenic lesion noted anteriorly and inferiorly thought to represent sequela of a splenic infarct (Figure 2).
