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).

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).
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.

The GDA pseudoaneurysms seen on the previous CT scan had resolved. (Figure 2).
