Abstract

Objective: To evaluate the value of CT in the diagnosis of gallbladder carcinoma and analyse the CT misdiagnostic causes of gallbladder carcinoma, in order to improve the diagnostic rate. Methods: The CT findings of twenty-six patients with gallbladder carcinoma confirmed by operation and pathology were analysed. The misdiagnostic causes were analysed and compared CT images with operation. Results: Gallbladder carcinoma is more common in female than in male. It is often found over the age of 50 years old. Four type of gallbladder carcinoma were recognized: ①Intraluminal mass of gallbladder accounted for 7.7%(2/26); ②Thickening of the gallbladder wall accounted for 15.4%(4/26); ③Infiltrating tumor accounted for 34.6%(9/26); ④Mixed type accounted for 42.3%(11/26). The major CT findings were classified as follows: mass, thicken wall, intraluminal mass, mass with stone, bileduct dilatation, direct hepatic invasion, hepatic metastasis. Conclusion: CT has important value in assessing gallbladder carcinoma. Analysis of CT characteristic of gallbladder carcinoma and misdiagnostic causes are useful in improving the diagnostic rate.
