黄色肉芽肿性胆囊炎的病理基础与超声表现关系初探

目的 探讨黄色肉芽肿性胆囊炎（XGC）临床病理特点、发病机制以及超声表现特征，以提高对本病的认识。方法回顾性分析经手术病理证实的黄色肉芽肿性胆囊炎26例的超声特征临床及手术病理资料。观察胆囊壁厚度、壁内光滑度及胆囊内有无结石，同时观察胆囊周围的变化。结果 26例患者中，观察其胆囊壁明显不规则增厚，多数病例切面可见淡黄或黄褐色大小不等的结节或斑点，有的呈息肉样突起。镜下见有特征性泡沫细胞肉芽肿形态。结论 XGC可能是由胆囊炎症、结石嵌顿和胆汁瘀积因素所诱导，与免疫反应有关的迟发性肉芽肿病变，少数病例可伴发腺癌。

To explore the relationship between the pathological basis and the performance of ultrasound of Xan thogranulomatous cholecystitis

Objective To explore the clinicopathological teatures, pathogenesis and the performance characteristics of Xanthogranulomatous cholecystitis （ XGC）, to enhance the awareness of the disease. Methods Retrospective analyzed ultrasound characteristics and surgical pathology data of 26 cases of Xanthogranulomatous choleeystitis. Results The obvious irregular thickening of the gallbladder wall and yellow or brown nodules were observed in most patients. Conclusion XGC was the delayed granulomatous disease with immune response,which might be caused by Cholecystitis disease, incarcerated stones and cholestasis factors.
