儿童颈部淋巴管瘤的CT诊断

目的:探讨颈部淋巴管瘤的CT表现及诊断价值.材料和方法:搜集经病理证实的颈部淋巴管瘤13例,CT扫描11例,平片2例.回顾分析其CT表现,并与手术病理结果对照.结果:根据颈部淋巴管瘤发生的部位将其分为3组,即肿块位于外三角区7例,颈后三角区5例,颈前区1例.最常见CT表现为边缘光整的囊性肿块,内有分隔,壁与分隔可强化.结论:颈部淋巴管瘤的CT表现多种多样,主要依赖于其生长部位及内容物的成分.CT对大多数病例定位定性诊断有重要价值.

CT Diagnosis of the Cervical Lymphangioma in Children

Purpose:To study the CT features of cervical lymphangioma and to evaluate the diagnostic value of CT findings.Materials and Methods:A retrospective and comparative study of CT(n=13)and X-Ray(n=2)findings of pathologically proved lymphangiomas and comparisons were made between these findings and operative and pathological results.Results:Patients were subdivided into three groups based on the location of the lesions.In the first group,the lesions were located in exterior triangle(n=7),in the other two groups,the lesions were located in posterior triangle(n=5)or in the front of neck(n=1).The most common CT appearance was a smoothly marinated cystic mass,while its wall and septum could be partially enhanced.Conclusion:The CT findings of cervical lymphangioma are varied,depending mainly on their locations and contents.CT is a useful imaging modality to locate,and to determine the nature of the lymphangioma.
