The Value of CT in the Diagnosis of Adult Bronchogenic Cyst
-
摘要: 目的:探讨CT扫描对支气管囊肿的诊断价值。方法:回顾性分析13例经手术和病理证实的成人支气管囊肿患者的CT表现。结果:纵隔型支气管囊肿3例,直径4～13cm,1例呈囊性,2例为软组织密度肿块,增强后其囊内容物及囊壁均未见强化,显示为高密度囊肿。肺内型支气管囊肿10例,直径0.5～6.0cm,含气和含液囊肿分别为2例和3例,均为边界清楚的圆形或卵圆形病灶,囊壁有强化,囊内容物未见强化;软组织肿块5例,1例合并肺段隔离症,1例边缘有环形钙化,3例为边缘模糊的不规则肿块。结论:CT平扫和增强对含气和含液支气管囊肿的诊断有特异性,对软组织密度支气管囊肿的鉴别诊断较困难,增强CT扫描有助于高密度囊肿的诊断。Abstract: Objective: To discuss the value of CT in the diagnosis of bronchogenic cysts. Methods: CT images in 13 histopathologically proved cases of bronchogenic cysts were retrospectively reviewed. Results: There were 3 mediastinal bronchogenic cysts. 1 cyst was of water of attenuation, 2 cysts were of soft-tissue attenuation and cyst contents do not enhance following administration of contrast material. There were 10 pulmonary bronchogenic cysts. 2 cysts was of air-water of attenuation and 3 cysts were of water of attenuation, were sharply marginated with smooth borders. 5 cysts were of soft-tissue attenuation, 1 was associated with same lobar sequestration, 1 was marginated with round calcification, and 3 were fuzzy marginated with irregular borders. Conclusion: We believe that a confident diagnosis of bronchogenic cyst could be done with CT in water and air-water attenuation cysts, soft-tissue cysts can be confused with other lesions, enhancemen CT could help the diagnosis of high attenuation cysts.
