Figure 1b. Post-ERCP pancreatitis in a 50-year-old man. ERCP was performed to check for a mass in the pancreatic tail, and the entire pancreatic duct was well opacified. The patient was readmitted 3 days after ERCP with abdominal pain and low-grade fever. CT was performed with oral and intravenous contrast material. (a) CT scan shows heterogeneous attenuation of the pancreas. Low-attenuation areas (*) suggest necrosis. Stranding of the peripancreatic fat is due to inflammation. There is thickening of the wall of the antrum of the stomach (arrow) secondary to local inflammation. (b) CT scan obtained inferior to a shows extensive stranding of the fat and thickening of the Gerota fascia on the right side (arrow). (c) CT scan shows fluid (arrow) in the dependent portion of the pelvis, a finding compatible with ascites.
