Abstract：Objective: To analyze CT characteristics of pancreatic carcinoma and chronic pancteatitis with mass in the head of the pancreas in order to improve its CT differential diagnostic accuracy. Materials and Methods: The clinical data of 30 cases with mass-type chronic pancreatitis in the head of the pancreas and carcinoma of head of pancreas were retrospectively analyzed. Results: The main CT differential points of the mass-type chronic pancreatitis and carcinoma of head of pancreas could be summarized as follows: ①calcification within the mass(17 cases, 0 case); ②contrast: lesions were raltive low density in portal venous phase(2 cases, 30 cases), and raltive equal density(28 cases, 0 case); ③shrink of the tail of pancreas(0 case, 18 cases), pancreatic pseudocyst(13 cases，1 case); ④dilatation of the pancreatic duct(18 cases, 25 cases), string of beads of dilation of pancreatic duct(15 cases, 4 cases), smooth dilation (3 cases, 21 cases), dilated pancreatic duct interrupt in the lesion area(4 cases, 12 cases), dilated pancreatic duct passed through the lesion area(14 cases, 1 case); ⑤dilatation of bile duct(25 cases, 12 cases), interrupt in the lesion area(2 cases, 21 cases), tapering from above downward(10 cases, 4 cases); ⑥no cross sign(0 case, 20 cases). Conclusion: The CT findings of the pancreatic head mass in chronic pancreatitis is characteristic, CT plays an important role in the of diagnosis and differential diagnosis of the two diseases.
