The pseudocyst was a 4.1-cm ovoid lesion with a thick wall and cystic mass not enhanced by contrast near the pancreatic head (Fig. 1).
Contrast-enhanced computed tomography image showing a 2.2-cm ovoid low-density lesion with an enhanced vessel near the pancreatic head, suggesting pseudoaneurysm.

Cr, and CRP were unremarkable. CT showed reduced size of the pancreatic HP with an enhanced vessel within the pseudocyst (Fig. 2).
a Contrast-enhanced computed tomography image showing a 2-cm ovoid low-density lesion with central collection near the pancreatic head in the arterial phase, suggesting pseudoaneurysm arising from a branch of the gastroduodenal artery. b Pancreatogram showing that the proximal portion of the major pancreatic duct was narrowed with slight dilation at the mid- and distal portions. c F/U contrast-enhanced computed tomography image showing no evidence of bleeding. d Contrast-enhanced computed tomography image showing an almost reduced cystic lesion near the pancreatic duct. The stent was noted in the main pancreatic duct.

Cr levels were unremarkable. CT showed reduced pseudocyst size at 2.2 cm; however, there was central contrast collection within the pseudocyst near the pancreatic head (Fig. 3a), suggesting pseudoaneurysm arising from a branch in the gastroduodenal artery (Fig. 3b). HP during pancreatography (Fig. 3b). Follow-up CT showed that the size of the pseudocyst was reduced to 2 cm, and there was no evidence of bleeding after 3 months (Fig. 3c) and with almost complete resolution after 6 months (Fig. 3d).
