摘要
目的 :探讨颈部先天性囊肿的CT表现特点及其诊断。材料和方法 :回顾性分析手术病理证实的颈部甲状舌管囊肿 9例 ,鳃裂囊肿 6例 ,淋巴管瘤 3例的CT平扫及增强扫描表现。结果 :颈部先天性囊肿表现为光滑、壁薄和无增强的肿块。甲状舌管囊肿多位于颈正中线 ,与舌骨关系密切 ,鳃裂囊肿多在胸锁乳突肌前缘 ,淋巴管瘤常位于颈后三角。结论 :CT能准确判断颈部先天性囊性肿块的性质和位置 ,结合临床能准确诊断。
Purpose: To explore the CT characteristics and diagnosis of the congential cystic masses in the neck. Materials and Methods: The plain and enhancement CT finding of 18 congenital cystic masses in the neck were analyzed retrospectively.There were 9 cases of thyroglossal dust cyst,6 cases of branchial cleft cyst,3 cases of lymphangioma in these masses. Results: Congenital cystic masses usually appeared as a smooth , wall circumscribed mass.The rim had no enhancemnet unless associated with inflammation. All 9 thyroglossal dust cysts located at the anterior median portion of the neck at the level of the hyoid bone. Six branchial cleft cysts located in front of the sternocleidomastoidells,and 3 lymphangiomas located in the posterior triangle of the neck. Conclusion: CT could correctively determine the nature and location of the cystic masses in the neck,combined withclinic data make a corrective diagnosis of congenital cystic masses.
