目的探讨支气管囊肿的CT表现特点及其诊断价值。方法对28例经手术病理证实为先天性支气管囊肿患者的CT表现进行回顾性分析,28例患者均行CT平扫及增强。结果28例支气管囊肿中,右肺10个,左肺9个;肺内型19例,纵隔型9例;含液囊肿13例,含气液囊肿8例,含气囊肿7例,其中多发肺囊肿8例,囊肿周围气肿5例,囊壁钙化3例,2例含曲霉菌。液囊肿增强扫描,囊壁增强,囊内无增强。结论大部分支气管囊肿有特征性的CT表现。CT在支气管囊肿的诊断及鉴别诊断中发挥重要作用。 Objective To investigate the CT features of bronchogenic cyst and its diagnostic value. Methods The CT findings of 28 patients with congenital bronchogenic cysts confirmed by surgery and pathology were retrospectively analyzed. All the 28 patients underwent CT scan and enhancement. Results Among the 28 cases of bronchial cysts, there were 10 right lungs and 9 left lungs; 19 were intrapulmonary types and 9 were mediastinal ones; 13 were fluid-containing cysts, 8 were gas-liquid cysts, 7 were air-cysts, 8 cases of cysts, emphysema around the cyst in 5 cases, cyst wall calcification in 3 cases, 2 cases with Aspergillus. Cyst enhancement scan, cyst wall enhancement, no enhancement in the capsule. Conclusions Most bronchial cysts have characteristic CT appearances. CT plays an important role in the diagnosis and differential diagnosis of bronchial cysts.
