200例儿童腺样体肥大的CT观察

CT observation of adenoid hypertrophy in 200 children

目的:探讨CT诊断儿童腺样体肥大的临床价值。方法:2018年2月-2019年4月收治腺样体肥大患儿200例,采用CT进行扫描检查,分析检查结果。结果:经CT重建图像显示,200例患儿均有不同程度的鼻咽腔变形变窄,其顶部及后壁可见软组织块影,密度均匀,前缘光滑或表面不平,后鼻孔出现不同程度的阻塞。腺样体厚度(A)/鼻咽腔宽度(N)平均值为0.72,其中轻度肥大25例(12.5%),A值为(12.5±0.6)mm,N值为(21.4±1.1)mm,A/N平均值为0.50~0.65;中度肥大80例(40.0%),A值为(14.7±0.7)mm,N值为(19.8±1.7)mm,A/N平均值为0.66~0.70;重度肥大95例(47.5%),A值为(16.1±1.8)mm,N值为(16.2±3.9)mm,A/N平均值为0.71~0.91。结论:CT是诊断儿童腺样体肥大的重要方法。

Objective:To explore the clinical value of CT in the diagnosis of adenoid hypertrophy in children.Methods:200 children with adenoid hypertrophy were selected from February 2018 to April 2019,all of them were scanned by CT,and the results were analyzed.Results:CT reconstruction showed that the deformation of nasopharynx became narrower in different degrees in all 200 children.Soft tissue block shadow was seen on the top and back wall of the nasopharynx,with uniform density,smooth front edge or uneven surface,and different degrees of obstruction in the posterior nostril.The average value of A(adenoid thickness)/N(width of nasopharynx)was 0.72,among them:25 cases of mild hypertrophy(12.5%),the A value was(12.5±0.6)mm,the N value was(21.4±1.1)mm,and the A/N value was 0.50~0.65.80 cases of moderate hypertrophy(40.0%),the A value was(14.7±0.7)mm,the N value was(19.8±1.7)mm,and the A/N value was 0.66~0.70.95 cases of severe hypertrophy(47.5%),A value was(16.1±1.8)mm,N value was(16.2±3.9)mm,and A/N value was0.71~0.91.Conclusion:CT is an important method for diagnosing adenoidal hypertrophy in children.
