超声诊断黄色肉芽肿性胆囊炎的临床分析

A Clinical Analysis with Xanthogranulomatous Cholecystitis Diagnosed by Colour Ultrasound

目的探讨超声诊断黄色肉芽肿性胆囊炎（XGC）的价值。方法回顾性分析21例经手术、病理证实的XGC，使用美国PHILIPAS-HD11及美国ATL3000彩色多普勒血流显像仪，探测胆囊大小、胆囊壁回声改变及胆囊壁上异常团块内的血流信号及其频谱。结果提示慢性胆囊炎伴结石13例，胆囊癌7例，胆囊腺肌症1例。术后病理回顾性分析均为XGC。结论当超声提示慢性胆囊炎反复发作并胆囊结石，胆囊壁明显增厚，胆囊壁上团块频谱呈低速低阻时，应高度考虑XGC可能。

Objective To investigate the value of colour Doppler ultrasound in the diagnosis of xanthogranulomatous cholecystitis（XGC）. Methods The colour Doppler ultrasound records（Philips-HD11 and ATL3000）of 21 cases with histopathologically confirmed XGC were analyzed retrospectively. The size of gallbladder, the echo of gallbladder wall, the blood flow signal and Doppler spectrum of gallbladder mass were documented. Results Colour Doppler ultrasound indicated chronic cholecystitis and gallstones in 13 cases, gallbladder carcinoma in 7 cases, adenomyomatosis in i case. These cases with XGC were confirmed by histopathology. Conclusion The ultrasonography findings of chronic cholecystitis with frequent at tacks, cholecystolithiasis, marked gallbladder wall low velocity and low resistance of blood suggestive of XGC. thickening or the Doppler spectrum of flow of gallbladder mass is highly suggestive of XGC.
