| 520 | 3 | |a Objectives: The purpose of this study is to evaluate the diagnostic performance of HRUS, CT, and MRI for differentiating xanthogranulomatous cholecystitis (XGC) from gallbladder (GB) cancer. Materials and Methods: Patients with surgically proven XGC (n=40) and GB cancer (n=44), who had undergone at least one HRUS (n=43), CT (n=82), or MRI (n=34) examination between 2000 and 2012, were included. Two radiologists retrospectively graded the likelihood of XGC or GB cancer using a 5-point confidence scale; they also assessed the imaging features. Statistical analyses were performed using ROC, ANOVA, and Fisher's exact test. Results: Diagnostic performance of MRI was better than HRUS for differentiating XGC from GB cancer (AUCs=0.867 and 0.911 vs. AUCs=0.818 and 0.86). However, HRUS showed a better performance than CT (AUCs=0.818 and 0.86 vs. AUCs=0.806 and 0.84) with moderate to excellent agreement (κ=0.48-0.83). Statistically common findings for XGC included non-focal thickening, smooth GB wall, presence of intramural nodules, type I enhancement of wall, transient hepatic attenuation difference, and continuity of mucosa (p<0.05). Co-existence of gallstones (OR=16.5), non-focal thickening (OR=14.7), and collapsed lumen (OR=13.0) on HRUS, and type I enhancement on CT (OR=3.52) were independently associated with XGC (p<0.05). Conclusion: Although MRI showed a better performance than both HRUS and CT, HRUS showed a better performance than CT. The co-existence of gallstones, non-focal thickening, and collapsed lumen on HRUS was independently associated with XGC. | |
