Abstract:
PURPOSE: To classify perivascular change in the celiac trunk and SMA occurring in pancreatic disease and toevaluate its significance in differential diagnosis. MATERIALS AND METHODS: In 73 patients with pancreaticdisease (42, acute pancreatitis; 14, chronic pancreatitis; 17, panreatic cancer) abdominal CT findings wereretrospectively reviewed. We defined " infiltration" as linear or irregular density and "thickening" as presenceof a soft tissue mantle surrounding the vessel, and statistically evaluated the usefulness of these factors forthe differential diagnosis of pancreatic diseases. RESULTS: In 13/42 cases of acute pancreatitis (31%), 4/14 ofchronic pancreatitis (28.6%), and 6/17 of pancreatic cancer (35.3%), periceliac infiltration was observed; thefrequencies were not statistically significant (p=0.916). Peri-SMA infiltration was demonstrated in 9/42 of acutepancreatitis (21.4%), 4/14 of chronic pancreatitis (28.6%), and 5/17 of pancreatic cancer (29.4%); again, thesefrequencies were not statistically significant (p=0.758). Thickening of the celiac trunk and SMA was observed onlyin pancreatic cancer, in 3/17 (17.6%) and 7/17(41.2%) cases, respectively, with statistical significance (p<0.05). CONCLUSION: Thickening of the celiac trunk and SMA is a valuable finding in the differential diagnosis ofpancreatic inflammatory disease and pancreatic cancer. When applied to the differential diagnosis of pancreaticdisease, perivaseular change should be classified as either infiltration or thickening.
