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.
背景
目前尚未描述儿童颈部淋巴结的正常测量值或特定大小标准。
目的
确定 CT 检查中儿童颈部淋巴结的正常测量值。
材料与方法
我们纳入了 142 名（年龄 1-17 岁）因高能外伤行颈部 CT 检查的儿童。我们评估了六个颈椎水平的轴位和冠状位 2mm 重建图像上的淋巴结。对于每个水平上最大的淋巴结，我们测量了长、短轴和长冠状轴的直径。
结果
在 142 名儿童中测量了 733 个淋巴结（62%为男性，38%为女性）。在轴位平面上，短轴的最大测量直径为 14mm，在轴位平面上长轴的最大测量直径为 24mm，在冠状位平面上长轴的最大测量直径为 28mm。颈椎水平 IV-VI 上年龄和淋巴结大小之间的 Pearson 相关系数在 0.19-0.47 之间。
结论
在其他方面健康的儿童中，颈 II 水平短轴直径超过 15mm 或所有其他颈椎水平超过 10mm 的淋巴结不常见。
