Abstract:Objective：To investigate the value of ultrasonography in distinguishing pancreatic cancer from focal pancreatitis. Methods：The ultrasonographic characteristics of cases of 30 pancreatic cancer and 18 cases of focal pancreatitis verified by surgery and/or pathology were studied retrospectively to determine the value of ultrasonography in their differential diagnosis. Results：There was significant difference between pancreatic cancer and focal pancreatitis in regard to the age of patients, the finding of pancreatic ductal structure and hyperechoic plaque within the pancreatic mass and rear echo. The focal pancreatitis patients were younger. The presence of pancreatic ductal structure and hyperechoic plaque in the pancreatic mass and enhanced rear echo suggested focal pancreatitis. Conclusions：Ultrasonography has certain value in distinguishing pancreatic cancer from focal pancreatitis.
