Figure 1 Contrast-enhanced computed tomography findings. A: Multiplanar computed tomography (CT) images (axial, coronal, and sagittal views) showing the portal vein coursing anterior to the duodenum (orange arrows), consistent with a preduodenal portal vein. The yellow dotted lines indicate the duodenal wall; B: Sagittal CT image demonstrating focal stenosis at the origin of the celiac artery (orange arrowhead), suggesting median arcuate ligament syndrome; C: Axial CT image showing multiple spleens (black arrow), consistent with polysplenia.
