黄色肉芽肿性胆囊炎的CT与MR影像分析

CT/MR features of xanthogranulomatous cholecystitis

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。

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 an-alyzed. 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, nod-ules in gallbladder wall and stones of gallbladder/bile duct are characteristics of XGC.
