Initial Presentation of a Pancreatic Mass.

Question: A 55-year-old African American man with a medical history of chronic pancreatitis, pancreatic mass, alcohol abuse, hypertriglyceridemia, gastroesophageal reflux disease, and essential hypertension presented to the emergency department with severe abdominal pain radiating to his back that was associated with diaphoresis and weight loss. The initial workup demonstrated acute pancreatitis. Prior radiologic studies were reviewed to better characterize the pancreatic mass. More recent computed tomography and MRI scans demonstrated an enlarging, cystic and septated mass within the pancreatic head with marked dilatation of the patient’s pancreatic, and intrahepatic and extrahepatic biliary ducts (MRI; Figure A). Additionally, there was evidence of peripancreatic fat infiltration and multiple enlarged peripancreatic lymph nodes. Ultrasonography had also shown that the mass was displacing the patient’s duodenum.
