Evaluation of CT in Malignant Obstructive Jaundice

Objective To evaluate CT technique in the diagnosis of malignant obstructive jaundice. Methods CT findings of 23 cases with surgically and pathologically proved malignant obstructive jaundice were analyzed. The tumors included cholangiocarcinoma (n=10), cancer of the head of pancreas (n=7), ampullary adenocarcinoma (n=5), carcinomal gallbladder (n=1), carcinoma of gallbladder complicated with cholangiocarcinoma (n=1). Results The CT characteristics of malignant obstructive jaundice included "soft rattan sign", "trancation sign", soft tissue mass, "double duct sign", lymph node intumescence and ascites. The move sign were detected, the more credible the diagnosis was. Conclusion Although there was some limitation in determining the specific disease, CT technique was accurate in determining the character of malignant obstructive jaundice.
