黄色肉芽肿性胆囊炎超声造影影像学特征分析

Contrast-enhanced ultrasonography of xanthogranulomatous cholecystitis

    摘要
  • 摘要:
    目的 探讨黄色肉芽肿性胆囊炎(xanthogranulomatous cholecystitis，XGC)的超声造影声像图特征。
    方法 收集2015年1月至2019年12月于复旦大学附属中山医院术后病理证实为XGC的24例患者术前的临床资料及超声声像图，分析其常规超声以及超声造影的声像图特征，并在造影前后分别给出超声诊断。
    结果 常规超声示胆囊轮廓清晰17例(70.8%)，模糊7例(29.2%)，仅2例(8.3%)胆囊黏膜线连续性佳，17例(70.8%)病灶内可测及彩色血流。超声造影后所有病例(100.0%)均可见增强，同时可见清晰的胆囊轮廓，黏膜线连续性佳者18例(75.0%)。超声造影与常规超声相比，在胆囊黏膜线的显示、胆囊轮廓的显示以及增厚胆囊壁血流检出率，差异均有统计学意义(P < 0.001，P=0.009，P=0.009)。
    结论 超声造影可为XGC的超声诊断提供更多的信息，相比于常规超声其诊断效能更高。

     

    Abstract:
    Objective To explore the characteristics of contrast-enhanced ultrasonography (CEUS) in xanthogranulomatous cholecystitis (XGC).
    Methods The clinical data of 24 patients with postoperative pathological diagnosis of XGC in the past 5 years were collected. The sonographic characteristics of conventional ultrasound and CEUS results were analyzed.
    Results Conventional ultrasound results showed that the contour of gallbladder was clear in 17 cases (70.8%), fuzzy in 7 cases (29.2%), and the continuity of gallbladder mucosa was good in only 2 cases (8.3%), rich color flow signal could be detected in 17 cases (70.8%). On CEUS, enhancement could be detected in all cases (100.0%), all cases showed clear gallbladder contour (100.0%), and the continuity of mucosal line was good in 18 cases (75.0%). Compared with conventional ultrasound, CEUS had significant difference in the display of gallbladder mucosal line, gallbladder contour, and the detection rate of thickened gallbladder wall blood flow (P < 0.001, P=0.009 and P=0.009).
    Conclusions CEUS might provide more diagnostic information for XGC, and be more helpful in the diagnosis of XGC than conventional ultrasound.
