case_images: Intestinal obstruction was excluded by abdominal x-ray scans, but unenhanced computed tomography (CT) scans showed high density lesion in the superior mesenteric vein (Figure 1).
case_images: Contrast-enhanced CT images performed on July 17 (A) and July 26 (B) showing thrombosis in portal vein, splenic vein, and superior mesenteric vein, and those on January 5, 2024 (C) showing cavernous transformation of the portal vein.

case_images: On July 17, 2023, contrast-enhanced CT scans showed that the portal vein, superior mesenteric vein, and splenic vein thrombus were occlusive (Figure 2A). On July 26, 2023, repeated contrast-enhanced CT scans showed that portal vein, superior mesenteric vein, and splenic vein were still occlusive with the development of collateral vessels (Figure 2B). Repeated contrast-enhanced CT scans showed that portal vein could not be identified, but was replaced by multiple collateral vessels (Figure 2C).
