目的 :探讨CT在支气管囊肿鉴别诊断中的价值。方法 :选取我院经手术及病理证实的支气管囊肿18例患者的CT资料进行回顾性分析。结果:18例患者中,5例为纵膈型支气管囊肿,其中2例为囊性,3例为软组织密度,CT值12-56HU,增强后未见强化。13例为肺内型支气管囊肿,直径0.5~5.5CM,平均3.5CM。13例中含气囊肿3例,1例呈薄壁圆形空腔,2例呈分叶状偏心空腔;含液囊肿4例,2例呈卵圆形,1例呈多房分隔状薄囊,增强后囊壁及囊内分隔均有强化,囊内容物未见强化;1例呈边缘模糊的厚壁球形病灶,囊内密度不均匀。软组织密度肿块6例,2例位于左肺下叶,1例肿块呈小结节状伴边缘环形钙化,3例为边缘模糊的不规则肿块。结论:CT扫描对于含气、含液支气管囊肿具有较高的诊断价值,对于软组织密度支气管囊肿的鉴别诊断较困难。
Objective: To investigate the value of CT in the differential diagnosis of bronchial cysts. Methods: CT data of 18 patients with bronchogenic cysts confirmed by operation and pathology in our hospital were retrospectively analyzed. Results: Of the 18 patients, 5 were mediastinal bronchial cysts, of which 2 were cystic, 3 had soft tissue density, and CT value was 12-56HU with no enhancement after enhancement. 13 cases of pulmonary bronchial cysts, diameter 0.5 ~ 5.5CM, an average of 3.5CM. Among the 13 cases, 3 cases had air cyst, 1 case had thin-walled circular cavity and 2 cases had lobulated eccentric cavity. There were 4 cyst fluid cysts, 2 oval cysts, 1 multi-septal cyst, After the enhancement of the cystic wall and cystic separation were enhanced, no enhancement of the contents of the capsule; 1 case was thick-walled spherical hemispheric lesions, the density of the cyst is not uniform. Soft tissue density in 6 cases, 2 cases in the left lower lobe, 1 case showed small nodules with peripheral annular calcification, 3 cases of irregular edge of the tumor. Conclusion: CT scan has high diagnostic value for gas-containing and liquid-containing bronchial cysts, and it is difficult to differentiate soft tissue density bronchogenic cysts.
