目的 提高对鳃裂囊肿CT表现的认识和诊断准确率。方法 回顾分析 10例经手术、病理证实的鳃裂囊肿的CT表现。结果 CT表现为位于颈前三角区 ,胸锁乳突肌前缘的囊性肿块 ,CT值 2 0～ 30Hu;合并感染 ,边界模糊 ,囊内密度增高 2例 ;囊壁强化 ,囊性部分无强化。第一鳃裂瘘管 1例 ,CT未显示。结论 CT检查对鳃裂囊肿可以清楚显示囊肿部位、形态、范围、强化特点及其与周围结构的关系 。
Objective To improve the recognization and the diagnostic accuracy of brachial cleft cyst (BCC) by CT scan. Methods CT findings of 10 BCC proved surgically and pathologically were retrospectively reviewed. Results BCC,CT number 22～33 Hu;with the enhanced wall and the non enhanced cystic part. If infections exist,the margin would be obscure and the internal density be increased. These cysts commonly located in the anterior triangle area of the neck or along the anterior border of the sternocleidomastoid muscle. The first brachial cleft fistula was not displayed. Conclusion CT scan can not only clearly show the location,enhanced characters and the relationship to the adjacent tissues of the BCC,but also can be possible to make the diagnosis of the BCC,but not the brachial cleft fistula.
