OBJECTIVE: To assess the value of ultrasonography in differential diagnosis of xanthogranulomatous cholecystitis (XGC) and wall-thickening type of gallbladder cancer (GBC).
METHODS: The clinical features and sonographic finding of 31 patients with XGC and 36 patients with wall-thickening type of GBC were retrospectively reviewed. The diagnosis of all cases was confirmed by pathological examination, and the ultrasonographic manifestations of the thickening of the gallbladder wall, intramural hypoechoic nodules, gallbladder mucosa line, gallbladder stones, biliary dilatation and gallbladder-liver boundary were compared between two groups.
RESULTS: There were significant differences in the intramural hypoechoic nodules, the continuous gallbladder wall mucosal line and dilatation of bile duct between XGC and GBC groups (all P<0.05), while no statistically significant differences in the other sonographic features(all P>0.05). In the six positive sonographic features of the XGC patients, the intramural hypoechoic nodules and the continuous mucosa line of the gallbladder wall had highest accuracy in the diagnosis of XGC(64.2% and 65.7%).
CONCLUSIONS: Intramural hypoechoic nodule and the continuous mucosal line are characteristic sonographic features of XGC, which can be used for the diagnosis of XGC.
