PURPOSE
The presence of ectopic thymic tissue is well known along the embryological descent track in the neck. The aim of this study was to detect the frequency of cervical thymic rests in children.
MATERIAL AND METHODS
Eighteen consecutive children had neck US performed using an ATL 5000 unit with a 12.5 MHz liner probe. The presence of small rests of thymic tissue was sought.
RESULTS
61% of the children had thymic tissue detected in the neck. Out of those with positive findings, 82% had a thymic rest on the right side, 9% on the left side and 9% had thymic rests bilaterally.
CONCLUSION
Small rests of ectopic thymic tissue in the cervical region are commonly seen in the paediatric age group. It is important to identify the thymic rests for what they are and avoid unnecessary anxiety or intervention.
目的
众所周知，在颈部胚胎发育路径沿途存在异位胸腺组织。本研究的目的是检测儿童颈部胸腺残体的发生率。
材料与方法
连续18名儿童接受颈部超声检查，使用ATL 5000设备及12.5MHz线性探头。寻找胸腺组织小残体的存在情况。
结果
61%的儿童颈部检测到胸腺组织。在这些有阳性发现的儿童中，82%右侧有胸腺残体，9%左侧有胸腺残体，9%双侧有胸腺残体。
结论
颈部异位胸腺组织小残体在儿童年龄组中很常见。重要的是要正确识别胸腺残体，避免不必要的焦虑或干预。
