Abstract：Objective: To study the CT and MR imaging diagnosis of xanthogranulomatous cholecystitis(XGC). Methods: The clinical and imaging data of 8 XGC patients confirmed by surgery and pathology in our hospital were collected, and their CT and MR manifestations and diagnostic thoughts were retrospectively studied. Results: Among the 8 cases of imaging data, the thickening of the gallbladder wall was found in 8 cases, including uniform diffuse thickening in 6 cases(75%) and localized thickening in 2 cases(25%). There were 7 cases(87.5%) of multiple intramural low-density nodules, 4 cases(50%) of biliary stones, 7 cases(87.5%) of “biscuit sign” enhancement of the gallbladder wall and complete mucosa, 7 cases(87.5%) of adjacent liver parenchyma and intestinal inflammatory infiltration, and 1 case(12.5%) of mild intrahepatic bile duct dilation. Conclusion: The CT and MR imaging features of XGC, including evenly diffuse thickening of gallbladder wall, uneven and “biscuit-like” enhancement, multiple low density and long T1, long T2 signal nodules in the gallbladder wall, choledocholithiasis, without disruption of bile-duct mucosa, inflammatory infiltration of adjacent tissues and without dilation of intrahepatic bile ducts, can provide a reliable evidence for doctor before surgical treatment.
