目的：探讨黄色肉芽肿性胆囊炎的CT、MR影像特征。方法：收集28例经手术和病理证实的黄色肉芽肿性胆囊炎患者的资料，回顾性分析其CT、MR影像表现。结果：28例患者中，胆囊壁增厚28例，其中弥漫性增厚22例（78.57%），胆囊/胆管结石21例（75%），胆囊壁内结节10例（35.71%），增强后黏膜线连续25例（89.29%），邻近结构浸润24例（85.71%）。结论：黄色肉芽肿性胆囊炎的主要特点是胆囊壁弥漫性增厚、增强后黏膜线连续、胆囊壁内结节及胆囊/胆管结石。
Abstract
Objective: The purpose of this study is to discuss the features of xanthogranulomatous cholecystitis(XGC) on CT /MR. Methods: Twenty-eight patients were confirmed XGC by surgery and pathology, and CT/MR manifestations were analyzed. Results: On CT or MRI, gallbladder wall thickening was shown in all 28 cases(100%), diffuse thickening was in 22 cases(78.57%), and stones of gallbladder/bile duct were shown in 21 cases(75%), with nodules in gallbladder wall in 10 cases(35.71%), continuous mucosal line enhancement in 25 cases(89.29%), and adjacent structure infiltration in 24 cases(85.71%), respectively. Conclusion: The co-existence of gallbladder wall diffuse thickening, continuous mucosal line enhancement, nodules in gallbladder wall and stones of gallbladder/bile duct are characteristics of XGC.
