[Abstract] Objective: To study the MRI featheres of xanthogranulomatous cholecystitis (XGC).Materials and Methods: A retrospective analysis was performed on 8 patients with pathologically proven XGC in this study. All patients underwent MRI scanning. The MRI feathers were: the patterns of wall thickening and enhancement, the presence of intramural nodules, mucosal line and presence of stones in the gallbladder. Liver parenchyma changes were also reviewed.Results: Gallbladder wall thickening occurred in all of the 8 cases. 6 cases were diffuse thickening and 2 cases were local thickening. Nodules were found in all of the 8 cases, which were low signal intensity on T1WI and high signal intensity on T2WI. Mucous membrane enhanced in all cases, in which 6 cases had intact mucosal line, 2 cases had interrupted mucosal line. All patients had cholecystolithiasis. Temporal enhancement of arterial phase in liver parenchyma in all cases.Conclusions: Frequent imaging manifestation of XGC were asymmetrical thickening of gallbladder wall, nodule in gallbladder wall, intact mucosal line and temporal enhancement of arterial phase in liver parenchyma.
