【摘要】 目的 评价高频超声在诊断小儿急性肠系膜淋巴结炎中的价值。方法 运用二维超声高频探头加压动态检查诊断155例急性肠系膜淋巴结炎,经抗感染治疗后10～15天超声复查。观察治疗前后淋巴结的超声表现。t检验比较治疗前后淋巴结大小的变化是否有统计学意义。结果 小儿急性肠系膜淋巴结炎典型的声像图特征是右侧中下腹部见数枚大小不等椭圆形低回声结节。治疗后10～15天复查肿大淋巴结有不同程度缩小，t检验治疗前后淋巴结大小变化差异有非常显著性(P<0.01)。结论 高频超声可作为小儿急性肠系膜淋巴结炎诊断的首选影像诊断方法。

    【Abstract】 Objective To evaluate the diagnostic value of high frequency ultrasonography in acute mesenteric lymphadenitis.Methods High frequency ultrasonography was used to examine 155 acute mesenteric lymphadenitis and the patients were reexamined 10 to 15 days after therapy.The sonographic appearances were analyzed before and after therapy.The difference of size of lymph nodes before and after therapy were compared( t test).Results The typical sonographic appearances were the presence of multiple enlarged lymph nodes shown as oval hypoechoic nodules with different size in the right inferior abdomen.The enlarged lymph nodes diminished in different degree 10 to 15 days after therapy and the difference before and after treatment was very significant.Conclusion High frequency ultrasonography may be the first choice of imaging examination in the diagnosis of acute mesenteric lymphadenitis. ......
