Abstract

Background

No normal measurements or specific size criteria have been described for cervical lymph nodes in children.

Objective

To determine the normal measurements of cervical lymph nodes in children on CT.

Materials and methods

We included 142 children (ages 1–17 years) who underwent cervical CT examination after high-energy trauma. We evaluated axial and coronal 2-mm reconstructions for lymph nodes at six cervical levels. For the largest lymph node at each level, we measured diameters in both the long and short axial axes and the long coronal axis.

Results

A total of 733 lymph nodes were measured in 142 children (62% boys, 38% girls). The greatest measured diameters were 14 mm for the short axis in the axial plane, 24 mm for the long axis in the axial plane and 28 mm for the long axis in the coronal plane. The Pearson correlation coefficient for age and lymph node size at Levels IV–VI was in the range of 0.19–0.47.

Conclusion

Lymph nodes with an axial short-axis diameter exceeding 15 mm for Level II and 10 mm for all other cervical levels are uncommon in otherwise healthy children.

摘要

背景

没有关于儿童颈淋巴结的正常测量或特定大小标准的描述。

目的

为了确定儿童在CT上颈淋巴结的正常测量。

材料和方法

我们纳入了142例高能外伤后接受宫颈CT检查的儿童（1至17岁）。我们评估了六个宫颈水平的淋巴结的轴向和冠状2毫米重建。对于每个水平上最大的淋巴结，我们测量了长轴和短轴以及冠状长轴的直径。

结果

在142名儿童中测量了733例淋巴结（男孩为62％，女孩为38％）。测得的最大直径在轴向平面中的短轴为14 mm，在轴向平面中的长轴为24 mm，在冠状平面中的长轴为28 mm。IV-VI级年龄和淋巴结大小的皮尔逊相关系数在0.19-0.47范围内。

结论

II级儿童的轴向短轴直径超过15mm且所有其他宫颈水平的淋巴结直径均超过10mm的淋巴结在其他健康儿童中并不常见。
