     【摘要】目的评价鳃裂囊肿及其合并症的CT表现及其诊断价值，提高对此病的认识。方法收集我院CT诊断并经手术证实的鳃裂囊肿15例(第二鳃裂囊肿14例，第三、四鳃裂囊肿1例，合并感染4例，癌变1例)，并复习有关文献，对其CT征象进行分析。结果单纯鳃裂囊肿表现为颈鞘外侧区病变，囊内密度均匀，囊壁薄，轻度强化；伴有感染时，囊壁不均匀增厚，强化明显，囊内密度增高，与周围组织有明显的粘连；癌变时囊壁结节样增厚，甚至呈实质性占位，并可侵犯周围组织结构。结论 CT可定位定性地诊断鳃裂囊肿，并可提示是否合并有感染，但鳃裂囊肿癌变时诊断困难。

    【Abstract】 Objective To evaluate the CT characteristics of the branchial cleft cyst(BCC) and its complications.Methods 15 cases with branchial cleft cyst ( 14 of second BCC and 1 of third BCC )proved by surgery and pathology,including 4 cases accompanied with infection and 1 case with canceration,were collected.The CT findings were analysed by combination with correlated literatues.Results BCC were dominatelyy located outside the carotid sheath structures.BCC without any complication appeared wellcircumscribed and homogeneous,no enhancements could be observed in the lesions.If infections exist,the margin would be obsecure,the internal density would be increased and an enhanced uneven wall would be observed;BCC with canceration could appear cystic wall nodules in the lesion and even a solid tumor mass.They could infiltrate into the adjacent tissues.Conclusion CT could not only make the diagnosis of BCC with a clear demonstration of its location,but also indicate whether with infections or not.It is difficult to diagnosis BCC with canceration with CT. ......
