Figure 16b.   Left paraduodenal hernia. Axial (a) and coronal (b) postcontrast CT scans show an encapsulated bowel loop (black arrows) in the left paraduodenal fossa. The inferior mesenteric vein (arrowheads) is displaced anterolaterally by the bowel loop and joins the SMV through the root of the SBM. Note the mesenteric fat and the jejunal vein (white arrows) within the bowel loop.
