The pancreas is the only organ in the body which reacts to trauma or inflammation by autolysis and the formation of a pseudocyst. Pancreatic pseudocysts are thought to develop secondary to rupture of a pancreatic duct with escape of pancreatic juice into the surrounding tissue or spaces. The fluid becomes loculated and a fibrous wall results form the secondary inflammation. There is no epithelial cell lining the cystic wall. The study was carried out to analyze the roentgenological findings associated with clinical symptoms and physical findings about 16 cases of pancreateic pseudocyst confirmed at Dept. of General Surgery. Chonnam National University Hospital form Jan. 1973 to May 1980. The results were summarized as follows ; 1. The ratio of male and female was 1.7 : 1 and the ages of most of patients ranged form 21 to 50 years. 2. Of our 16 cases, 7 cases had a history of pancreatitis, 5 cases trauma but no specific past history was obtained in 2 cases. 3. Most frequent ou standing clinical symptoms and signs were abdominal pain(87.5%), tenderness(81.3%) and palpable mass (68.8%). 4. In laboratory findings , serum amylase level was elevated in 9 cases , leukocystosis in 5 cases and significant senemia on admisson in 6 cases.5. Radiographic examination, especially UGI series was most useful diagnostic aid . The most common and important radiologic finding was anterior displacement of stomach and extrinsic compression(87.5%). 6. The location of pseudocyst was in body(62.5%), tail (25.3%)and head (12.5%) of the pancreas in order.
