摘要

目的:本研究的目的是确定从新生儿到18岁的正常胸腺在对比增强多探测器计算机断层扫描(MDCT)上的形态学特征和测量。材料与方法:对464例平均年龄±SD为8.43±5.60岁的儿童的MDCT扫描资料进行回顾性评价。确定每个年龄组胸腺的形状、边缘、侧边优势、密度和测量值。结果:胸腺中间呈三角形,外侧呈直状是儿童胸腺最常见的形态特征。胸腺前后径平均17.32±4.58 mm,胸腺横向径平均29.99±11.42 mm。右胸腺叶宽度平均值为20.66±5.36 mm,厚度平均值为15.15±6.76 mm;左侧分别为26.14±7.85 mm和14.91±5.51 mm。胸腺横径和胸腺叶尺寸随年龄的增长而明显减小,胸腺前后径与年龄无显著相关性。女孩胸腺衰减值高于男孩,但性别差异无统计学意义(63.8±22.4 HU比60.1±25.3,p = 0.164)。结论:我们的研究提供了对儿童正常胸腺外观更好的理解,可以帮助准确诊断,避免不必要的,昂贵的和侵入性的干预。

Multidetector Computed Tomographic Evaluation of the Normal Characteristics of the Thymus in the Pediatric Population.

Objectives: The objective of the present study was to determine the morphologic features and measurements of the normal thymus on contrast-enhanced multi-detector computed tomography (MDCT) in subjects from the newborn period up to 18 years of age.

Materials and methods: The MDCT scans obtained from 464 children with a mean age ± SD of 8.43 ± 5.60 years were retrospectively re-evaluated. The shape, margins, side predominance, density, and measurements of the thymic gland were defined for each age group.

Results: A triangular thymic shape with a middle location and straight lateral contours were the most frequently seen morphologic features in children. The mean anteroposterior and transverse diameter of the thymus was 17.32 ± 4.58 and 29.99 ± 11.42 mm, respectively. The mean values for the width and thickness were 20.66 ± 5.36 and 15.15 ± 6.76 mm for the right thymic lobe, respectively; and 26.14 ± 7.85 and 14.91 ± 5.51 mm for the left, respectively. The transverse diameter of the thymus and thymic lobe dimensions decreased significantly with age, however, the anteroposterior diameter of the thymus was not significantly associated with age. Girls had higher mean thymic attenuation values compared to boys, however, this gender difference was not statistically significant (63.8 ± 22.4 HU vs. 60.1 ± 25.3, p = 0.164).

Conclusion: Our study provides a better understanding of the normal thymic appearances in children that can aid in accurate diagnosis and avoid unnecessary, costly, and invasive interventions.
