小儿正常肠系膜淋巴结的超声表现

The ultrasound characteristics of mesenteric lymph nodes in normal children

目的认识正常小儿肠系膜淋巴结的超声表现。方法随机选择138例1～12岁正常小儿按年龄分成三组,应用高频多普勒超声诊断仪进行腹部肠系膜淋巴结扫描,记录大小、形态、数量、内部回声、血供情况,并进行统计学分析。结果大部分小儿可探到肠系膜淋巴结,人均3.6个。淋巴结大小男、女组无差异,并且随着年龄的增长淋巴结大小逐渐变小,数目逐渐减少。结论确立正常小儿肠系膜淋巴结特征,为临床诊断小儿淋巴结疾病提供了良好的参考依据。

Objective Understanding the ultrasound characteristics of mesenteric lymph nodes in normal children. Methods 138 cases of 1 to 12-year-old normal children were randomly selected and divided into three groups by age. Their abdomen mesenteric lymph nodes were scanned with high-frequency doppler ultrasound diagnostic apparatus and the size, shape, quantity, internal echo and the blood supply situation of the nodes were recorded. Results The mesenteric lymph nodes were detected in a majority of children. There were 3.6 mesenteric lymph nodes per capita. No differences were found in the size of lymph nodes between boys and girls. The size and number of lymph nodes reduced with the growth of age. Conclusion Establishing the characteristics of mesenteric lymph nodes of normal children will serve as a good reference for clinical diagnosis of children＇s lymphatic disease.
