摘要
目的探讨多层螺旋CT(MSCT)对黄色肉芽肿性胆囊炎的诊断价值。材料与方法回顾性分析6例经手术病理证实黄色肉芽肿性胆囊炎MSCT表现,结合文献分析其CT特征。结果 6例胆囊壁均弥漫性或对称性增厚。5例弥漫增厚胆囊壁内见低密度结节。6例均见强化粘膜线,5例粘膜线连续,1例粘膜线局部裸露。2例侵犯肝实质动态增强见一过性强化。4例无肝内胆管扩张。6例均有胆囊结石,4例同时合并肝内外胆管结石。结论胆囊壁弥漫性或对称性增厚、增厚胆囊壁内低密度结节、连续或裸露的强化粘膜线、侵犯肝实质时肝动脉期一过性强化、肝内胆管不扩张等征象对黄色肉芽肿性胆囊炎的诊断有重要价值。
Objective To study the value of multi-slice spiral CT （MSCT） in xantho^ranulomatous cholecvstitis（XGC）. Methods Six patients of XGC proved by padlol- of were examined with MSCT. The findings of MSCT were retrospectively analyzed together with review of the literature. Resullx The diffuse or svmmetrv thickened gallbladder wall were detected in 6 patients, the hvpo-derrse nodules in the thickened walls were found in 5 patients. The enhanced mucosal lines were observed in 6 patients, in which five were continuous, one was denuded. Two patients could find transient hepatic abnormal enhance- ment in the hepatic arterial phase because of hepatic infiltration. The absence of intra-hepatic bile duct dilatation was showed in 4 cases. There were cholecvstolithiasis in 6 cases, of which 4 cases associated with intra-hepatic bile duct calculi. Conclusion CT features of diffuse or symmetry thickened gallbladder wall, the presence of hypo-dense nodules in the thickened walls, continuous or denuded enhanced mucosal tines, the presence of transient hepatic abnor- mal enhancement in the hepatic arterial phase when hepatic parenchvma was invaded, absence of intra-hepatic bile duct dilatation are strongly suggestive ot XGC.
