Objective To analyze the MRI features of xanthogranulomatous cholecystitis (XGC). Methods A retrospective analysis was made on MRI findings for 13 cases of pathologically confirmed XGC. Results The gallbladder wall of the 13 XGC cases were thickened in varying degrees, 8 cases with thickness of 3~10 mm and 5 cases with thickness of more than 10 mm. Diffuse thickening of gallbladder wall occupied in 12 cases and focal thickening in 1 case. All the 13 cases reflected gallbladder wall signal unevenness. Cholecystolithiasis was found in 13 cases, bile duct stones in 3 cases and bile duct dilatation in 3 cases. Peripheral small lymph nodes were reported in 3 cases. Peripheral adipose space was blurred in 8 cases and infiltrated into duodenal bulb in 1 case. Four cases underwent enhanced scan, all of which showed uneven enhancement of gallbladder wall, continuous enhancement of mucosa and infiltration into adjacent liver parenchyma. Conclusion MRI can show many features of XGC, especially enhanced MRI has high value for preoperative diagnosis of XGC.
