Hemosuccus pancreaticus caused by gastroduodenal artery pseudoaneurysm associated with chronic pancreatitis: A case report and review of literature

Figure 1 Contrast-enhanced computed tomography of the abdomen. A: Noncontrast-enhanced computed tomography revealed pancreatic swelling, multiple granular calcifications in the parenchyma, pancreatic duct dilatation in the body and tail, and a circular hypointense opacity surrounded by a slightly hyperintense wall in the pancreatic head; B: Obvious enhancement in the pancreatic head lesion in the arterial phase, with a computed tomography value of approximately 195 HU and without enhancement of the surrounding tissue. The lesion is closely related to the gastroduodenal artery (arrow); C: Continuous enhancement in the pancreatic head lesion in the venous phase, with a computed tomography value of approximately 125 HU and without enhancement of the surrounding tissue; D: Sagittal view of multiplanar reconstruction showing the adjacent relationship between the pancreatic head lesion and surrounding structures.
