Fig. 1A61-year-old woman with duodenal diverticulitis. Axial
unenhanced CT scan at level of head of pancreas (P). Ill-defined 2.5-cm mass
(arrow) is present posterior to pancreas and second portion of
duodenum. Associated soft-tissue stranding is present.
Fig. 1B61-year-old woman with duodenal diverticulitis. Axial
contrast-enhanced CT scan performed 1 week later shows mass is smaller and
more well-defined (arrow), contains air, and has appearance of
duodenal diverticulum. Amount of soft-tissue stranding has decreased.
Fig. 2A53-year-old woman with duodenal diverticulitis. Axial
contrast-enhanced CT scan shows air-containing 2.5-cm mass (large
arrow) posterior to mesenteric vessels (small arrow) and
uncinate process of pancreas with adjacent soft-tissue stranding.
Fig. 2B53-year-old woman with duodenal diverticulitis. Coronally
reformatted image reveals contrast-filled diverticulum (arrow)
arising from third portion of duodenum.
Fig. 2C53-year-old woman with duodenal diverticulitis. Coronally
reformatted image reveals second diverticulum (arrow) that is
partially air filled and thick walled with surrounding soft-tissue stranding
caused by acute duodenal diverticulitis.
