目的探讨黄色肉芽肿性胆囊炎(XGC)的CT表现,以提高黄色肉芽肿性胆囊炎诊断水平。方法分析经手术、病理证实的11例黄色肉芽肿性胆囊炎的CT、临床及手术病理资料。观察胆囊壁厚度、壁内低密度结节、胆囊内壁、黏膜线、胆囊壁及受累肝组织强化程度、胆囊内有无结石,以及胆囊周围的变化。结果11例均见不同程度的胆囊壁增厚及壁内结节,9例胆囊壁内面光滑,6例显示黏膜线,3例胆囊增大,4例缩小,4例发现胆囊结石,6例侵犯肝脏,3例胆囊周围炎性浸润,6例伴有胆道扩张。结论增厚的胆囊壁内低密度结节(三明治征)和完整的黏膜线较具特征性。 Objective To investigate the CT findings of yellow granulomatous cholecystitis (XGC) in order to improve the diagnosis of yellow granulomatous cholecystitis. Methods The CT, clinical and pathological data of 11 cases of granulomatous yellow cholecystitis confirmed by operation and pathology were analyzed. The gallbladder wall thickness, low-density nodules in the wall, the gallbladder wall, mucosal line, gallbladder wall and affected liver tissue enhancement, gallstone in the gallbladder and changes around the gallbladder were observed. Results In 11 cases, gallbladder wall thickening and nodules in the wall were observed. The gallbladder wall was smooth in 9 cases, mucosal line in 6 cases, gallbladder enlargement in 3 cases, narrowing in 4 cases, gallstones in 4 cases and infiltration in 6 cases Liver, 3 cases of inflammatory infiltration around the gallbladder, 6 cases with biliary dilatation. Conclusion Thickened gallbladder wall low density nodules (sandwich sign) and the complete mucosal line more characteristic.
