中文摘要：

目的：探讨胆囊腺肌增生症的超声造影表现及特征。方法：回顾性分析2011年5月—2014年4月经手术病理证实的30例胆囊腺肌症的病例资料。结果：30例胆囊腺肌症动脉期高增强25例、等增强5例。病灶内血管形态,9例显示对比剂先进入增厚囊壁的黏膜层、随即进入浆膜层,呈周边环状增强（30%,9/30）。病变开始增强时间（13.83±3.38）s,消退时间（56.29±28.91）s。术前常规超声诊断胆囊腺肌增生症5例（16.7%,5/30）,超声造影诊断26例（86.7%,26/30）。11个病灶常规超声检查边界显示不清,超声造影病灶边界均显示清晰。结论：胆囊腺肌症超声造影具有一定特征性,能显著提高胆囊腺肌增生症的诊断准确率,值得临床应用推广。

英文摘要：

Objective： To investigate the enhancement pattern and parameters of contrast enhanced ultrasound（CEUS） in gallbladder adenomyomatosis. Methods： Thirty pathologically proven gallbladder adenomyosis in 30 patients who had undergone CEUS preoperatively were included in this study. Various contrast enhancement patterns and parameters were retrospectively analyzed. Results： Twenty-five lesions showed hyper-enhancement during the arterial phase and 5 lesions showed iso-enhancement. As to the pattern of intralesional vascularity, 9 lesions showed peripheral rim-like hyper-enhancement（30%, 9/30）.The contrast agent entered the mucosa firstly and then theserosa of the gallbladder wall. The arrival time of contrast agent to the lesion was（13.83±3.38） s and the washout time was（56.29±28.91） s. Preoperatively, two readers using conventional ultrasound made 5 correct diagnosis of gallbladder adenomyomatosis among the all 30 cases（16.7%, 5/30） whereas, using CEUS they made 26 correct ones（86.7%, 26/30）. Besides, 11 lesions which were poorly defined using conventional ultrasound were well defined using CEUS. Conclusions： Enhancement patterns and parameters of CEUS may be useful in the noninvasive diagnosis of gallbladder adenomyomatosis.
