目的:探讨异位支气管囊肿的CT诊断价值。方法:结合文献,对经病理证实的2例异位支气管囊肿的CT表现进行回顾性分析。结果:2例异位支气管囊肿中,1例位于胃食管区,另1例位于左腹膜后区。两例CT平扫均表现为边界清晰、密度较高的肿块影,增强扫描表现为囊性部分未见明显强化;其中一例病灶有厚壁,壁均匀光滑,增强表现为环形强化,另一例病灶内部可见分隔及钙化。结论:CT平扫加增强扫描有助于诊断及鉴别诊断,CT有助于敏感地发现异位支气管囊肿,能清晰地显示病灶的部位、形态、大小、边界、密度及增强表现,确诊依赖于病理诊断。
Objective: To investigate the value of CT in diagnosis of ectopic bronchial cyst. Methods: According to the literature, CT findings of 2 cases of ectopic bronchogenic cysts confirmed by pathology were analyzed retrospectively. Results: In two cases of ectopic bronchial cysts, one was located in the gastroesophageal area and the other one was located in the left retroperitoneal area. Two cases of CT scan showed a clear boundary and high density of mass shadow, enhanced scanning showed no significant enhancement of the cystic part; one case of thick lesions, the wall is uniform and smooth, the enhancement showed ring enhancement, another case of lesions Internal visible separation and calcification. Conclusion: CT scan and enhanced scan are helpful to the diagnosis and differential diagnosis. CT is helpful to detect the ectopic bronchial cyst sensitively, and can clearly display the location, shape, size, boundary, density and enhancement of the lesion. The diagnosis depends on Pathological diagnosis.
