摘　　要：目的探讨超声造影对诊断黄色肉芽肿性胆囊炎(xanthogranulomatous cholecystitis,XGC)的价值。方法选取术前行常规超声及超声造影检查的XGC 14例,同时行增强CT检查的9例,分析图像特点,总结其特征表现。结果14例病灶胆囊壁均增厚,13例伴囊腔内结石,1例伴胆总管结石。超声造影4例病灶增厚的囊壁动脉期出现小灶性不增强区,9例胆囊黏膜线完整清晰,6例浆膜线完整清晰,4例胆囊旁肝实质有减退区。增强CT组与超声造影组囊壁动脉期强化程度具有显著差异,超声造影(64.3%)诊断正确率较增强CT(44.4%)高。结论超声造影对胆囊病灶动脉期增强特点的观察更具优势,对XGC更具诊断价值。Objective To investigate the diagnostic value of contrast-enhanced ultrasound for xanthogranulomatous cholecystitis(XGC).Methods There were 14 cases of XGC who underwent preoperative ultrasound and contrast-enhanced ultrasound(CEUS)examination in our hospital from February 2016 to April 2020 and 9 cases who underwent contrast-enhanced CT examination at the same time.The images were analyzed to summarize the performance of XGC.Results All 14 gallbladder walls were thickened,13 cases were with intracystic stones,1 case was with bile duct stones.There were 9 cases that the gallbladder mucosal line was continuous and 6 cases that the gallbladder serous line was intact and clear.And the liver parenchyma adjacent to the gallbladder was with focal reduction area in 4 cases.There was significant difference of the degree of gallbladder enhancement between group contrast-enhanced CT and contrast-enhanced ultrasound.The diagnostic accuracy of the contrast-enhanced ultrasound was higher than contrast-enhanced CT.Conclusion Contrast-enhanced ultrasound has more advantages in the observation of the enhancement characteristics of the arterial phase of gallbladder lesions,and has more diagnostic value for XGC.
