Figure 3. Mild interstitial oedematous pancreatitis (IEP) in a 57-year-old female (CRP level of 28 mg/L, Ranson, BISAP, Marshall, APACHE II, CTSI, and EPIC of 1, 1, 0, 4, 4, and 3 points, respectively; there was no infection, procedure, ICU admission, organ failure, or death on this patient). Abdominal axial contrast-enhanced CT at the portal phase (A) showed there was a small amount of acute peripancreatic fluid collection (APFC) around the pancreas. Axial chest image CT (B) showed there was a small amount of bilateral pleural effusion.
Figure 4. Severe necrotizing pancreatitis (combined pancreatic and peripancreatic) in a 42-year-old male (CRP level of 253 mg/L, Ranson, BISAP, Marshall, APACHE II, CTSI, and EPIC of 5, 4, 18, 6, 6, and 3 points, respectively; positive for infection and organ failure while no procedure was done, no ICU admission, or death on this patient). Abdominal axial contrast-enhanced CT at the portal phase (A) showed there was a large amount of acute necrotic collection (ANC) around the pancreas. Axial chest image CT (B) showed there was a large amount of left pleural effusion.
