Learning objectives Review the CT findings in acute pancreatitis based on the revised Atlanta classification. Discuss the  complications of acute pancreatitis.
Read more Background Acute pancreatitis is one of the common causes of acute abdominal pain, necessitating hospital admission due to its high mortality and morbidity risk. CT plays an important role in evaluating the severity of acute pancreatitis including the presence of necrosis and infection, and determine the presence of local complications.According to the revised Atlanta classification, the diagnosis of acute pancreatitis requires at least two of the following three features:  Abdominal pain consistent with acute pancreatitis Elevated serum lipase or amylase at least 3...
Read more Findings and procedure details According to the revised Atlanta classification, the morphological imaging findings of acute pancreatitis are stratified into 2 main categories: interstitial edematous pancreatitis and necrotizing pancreatitis.  Interstitial edematous pancreatitis (IEP) IEP is more common and represents non necrotizing inflammation of the pancreas. On contrast enhanced CT the imaging features include: Pancreas appears diffusely enlarged due to inflammatory edema. The parenchyma demonstrates homogenous enhancement, occasionally it might be less avid, however with absence of pancreatic or peri-pancreatic necrosis. The peri-pancreatic fat may show fat stranding and/or peripancreatic...
Read more Conclusion CT is the initial technique of choice for assessing acute pancreatitis. Understanding the imaging features based on the revised Atlanta classification allows a clear understanding of the range of imaging findings, thereby allowing the radiologist to provide meaningful reports which aid in patient management.
