彩色多普勒超声诊断小儿肠系膜淋巴结炎93例资料分析

Analysis of Color Doppler Ultrasound in Diagnosis of Mesenteric Lymphadenitis in Children(A Report of 93 Cases)

目的探讨彩色多普勒超声对小儿肠系膜淋巴结炎的诊断价值。方法回顾性分析我院2006年1月～2010年12月采用彩色多普勒超声诊断小儿肠系膜淋巴结炎93例的临床资料和影像特征。结果93例超声均见多发性肠系膜淋巴结增大，二维声像图提示增大的淋巴结长径以8—20mm多见，形态规则，呈椭圆形或扁圆形，边界光滑整齐，呈均匀性增大，皮质和髓质显示清楚，髓质增宽、增强，皮质相对变窄，肾形结构存在，纵横比均≥2。48例位于右侧腹，45例位于脐周。结论彩色多普勒超声检查对小儿肠系膜淋巴结炎有重要的鉴别诊断价值，应用腹部探头检查可排除其他病因，高频探头能清晰显示肠系膜淋巴结。

Objective To evaluate the value of color Doppler ultrasound in the diagnosis of mesenteric lymphadenitis in children. Methods The clinical data and sonograms of 93 children with mesenteric lymphadenitis diagnosed by color Doppler ultrasound from January 2006 to December 2010 were retrospectively analyzed. Results Sonograms of all the children revealed enlargements of lymph nodes. Two dimensional sonograms showed that the common lengths of enlarging lymph node was 8 -20 mm, and the characteristics of lymph node were regular shape, ellipse or oblateness, smooth borders, equal enlargements, clear appearance of cortex and medullary substance, widened and enhanced medullary substance, narrowed cortex, kidney shaped structure, and aspect ratio ≥2. The lesions were located on the right abdomen in 48 patients, and around navel in 45. Conclusion Color Doppler ultrasound plays an important role in differential diagnosis of mesenteric lymphadenitis in children. It can exclude other diseases with the help of abdomen probe, and high frguency probe can detect mesenteric lymphonodi.
