摘要
目的:本研究回顾性研究黄色肉芽肿性胆囊炎(XGC)CT和MR影像诊断思路的分析。方法:收集8例经我院手术和病理结果确诊的XGC患者的临床及影像资料,回顾性研究其CT、MR表现及诊断思路。结果:8例影像资料中,胆囊壁不同程度增厚8例,包括均匀弥漫性增厚6例(75%)和局限性增厚2例(25%);壁内多发低密度结节7例(87.5%),胆道结石4例(50%),胆囊壁“夹心饼干征”样强化及黏膜线完整7例(87.5%),邻近肝实质及肠管炎性浸润7例(87.5%),肝内胆管轻度扩张1例(12.5%)。结论:XGC的影像诊断思路是通过观察XGC的CT及MRI平扫及增强特征性表现:包括胆囊壁均匀弥漫性增厚、不均匀强化,呈“夹心饼干征”样改变、胆囊壁内多发低密度及长T1长T2信号结节、胆道多合并结石、内壁黏膜线完整、炎性浸润邻近周围组织及肝内胆管多无扩张,以提高XGC术前诊断准确率,可为外科医生手术治疗的选择提供可靠依据。
Objective: To study the CT and MR imaging diagnosis of xanthogranulomatous cholecystitis(XGC). Methods:The clinical and imaging data of 8 XGC patients confirmed by surgery and pathology in our hospital were collected, and their CT and MR manifestations and diagnostic thoughts were retrospectively studied. Results: Among the 8 cases of imaging data,the thickening of the gallbladder wall was found in 8 cases, including uniform diffuse thickening in 6 cases(75%) and localized thickening in 2 cases(25%). There were 7 cases(87.5%) of multiple intramural low-density nodules, 4 cases(50%) of biliary stones, 7 cases(87.5%) of "biscuit sign" enhancement of the gallbladder wall and complete mucosa, 7 cases(87.5%) of adjacent liver parenchyma and intestinal inflammatory infiltration, and 1 case(12.5%) of mild intrahepatic bile duct dilation.Conclusion: The CT and MR imaging features of XGC, including evenly diffuse thickening of gallbladder wall, uneven and"biscuit-like" enhancement, multiple low density and long T1, long T2 signal nodules in the gallbladder wall, choledocholithiasis, without disruption of bile-duct mucosa, inflammatory infiltration of adjacent tissues and without dilation of intrahepatic bile ducts, can provide a reliable evidence for doctor before surgical treatment.
