N/A To investigate the utility and accuracy of sonographic patterns of gallbladder wall in the differentiation of malignant and benign ascites, gallbladder wall patterns were observed using ultrasound in 17 patients with malignant ascites and 73 patients with benign ascites. Three gallbladder wall patterns were recognized: A, single layered, nonthickened wall; B, single layered, thickened wall; and C, double layered, thickened wall. Pattern A was found more frequently in patients with malignant ascites, while pattern B and C were detected more frequently in patients with cirrhotic ascites. If nonthickened gallbladder wall is used as a criterion for prediction of maligant ascites, the sensitivity is 59.0% and the specificity is 93.8%. This suggests that sonographic examination of the gallbladder wall may be a useful method for the differentiation of malignant from benign ascites.
