case_images: Contrast-enhanced computed tomography scan of the abdomen on the day of admission of a 49-year-old man with severe acute pancreatitis revealed gastroduodenal artery pseudoaneurysms without extravasation of contrast medium (thick white arrows) in the (A) axial view and (B) coronal view. One was 6 mm in diameter and the other was 4 mm in diameter. The pseudoaneurysms were surrounded by a small hematoma (thin white arrows). The pancreatic parenchyma was significantly swollen and enlarged, but not necrotic (black arrows).

case_images: Contrast-enhanced computed tomography (CT) scan of the abdomen was consistent with acute pancreatitis with intact GDA pseudoaneurysms surrounded by a small hematoma (Figure 1).
case_images: Contrast-enhanced computed tomography (CT) scan of the abdomen of a 49-year-old man with severe acute pancreatitis on hospital day 2 with (A-C) axial and (D-F) coronal views. Pseudoaneurysms of the gastroduodenal artery had resolved, however, the hematoma around the pancreatic head had enlarged (15.6 cm x 12.3 cm x 7.1 cm) occupying the right retroperitoneal space (thin white arrows). Interstitial edema of the pancreas was more evident than on the CT scan from admission (black arrows). There was no necrosis seen.
