Abstract

Authors retrospectively analysed abdominal CT findings of 120 patients, of whom the CT was done under the clinical impression of pancreatic diseases. These include 20 patients of acute pancreatitis, 12 patients of chronic pancreatitis, and 41 patients of pancreatic tumor. Remaining 47 patients were proved to have normal pancreas. CT permitted correct diagnosis in 108 of 120 patients with diagnostic accuracy 91%, sensitivity 95%, and specificity 79%. Predictive value of positive CT diagnosis was 93% and that of negative diagnosis was 82%. Commonly observed CT findings of acute pancreatitis were diffuse pancreatic enlargement (75%), obliteration of peripancreatic fat planes (70%), peripancreatic "Dirty fat" (50%), and renal fascial thickening (50%). Abscess formation, pseudocyst formation, phlegmon, and fluid collection were the complication so acute pancreatitis in order of frequency. In chronic pancreatitis, pancreatic calcification was the most frequent (58%) and specific CT finding. Pancreas size were normal in 2 patients (16%), atrophic in 5 patients (42%), and enlarged in 5 patients (42%). Of 40 patients with pancreatic cancer, 36 patients showed pancreatic mass on CT, and 18 were with central low density. Other findings of pancreatic cancer were obliteration of peripancreatic fat planes (60%), biliary dilation (30%), and secondary pancreatitis (18%). Liver and lymph nodes metastases were found in 27 patients (68%) at the time of CT scanning.
