摘要
目的分析黄色肉芽肿性胆囊炎(XGC)的不典型CT征象。方法搜集8例经病理证实但CT征象不典型的XGC患者的临床与CT资料,与组织学对照,分析其不典型的影像特征。结果 8例XGC的胆囊壁内均没有发现明确低密度结节,6例胆囊壁为局限性增厚,增强扫描5例病变为轻度强化,1例无明显强化,7例胆囊黏膜线不连续强化。结论当XGC CT表现不典型时,即局限性增厚的胆囊壁内未见明确低密度结节、无明显强化或轻度强化、黏膜线不连续等,需结合临床实验室资料,综合分析以便做出正确诊断。
Objective To analyze the atypical CT signs of Xanthogranulomatous Cholecystitis. Methods The clinical and CT data of 8 patients with xanthogranulomatous cholecystitis confirmed by pathology but atypical CT signs were collected and compared with histology to analyze the atypical imaging features. Results In 8 cases of Xanthogranulomatous Cholecystitis,no clear low-density nodules were found in the gallbladder wall,6 cases of gallbladder wall had localized thickening.Enhanced scan showed mild enhancement in 6 cases,no enhancement in 1 case,and discontinuous enhancement of gallbladder mucosa in 7 cases. Conclusion When the CT manifestations of xanthogranulomatous cholecystitis are atypical,that is,there are no definite low-density nodules in the gallbladder wall with limited thickening,no obvious enhancement or mild enhancement,and mucosal line discontinuity,it should be combined with clinical laboratory data for comprehensive analysis to make the correct diagnosis.
