摘　　要：目的探讨先天性支气管肺囊肿的CT表现。方法回顾分析经手术病理证实的先天性支气管肺囊肿49例的发病部位、数目、大小、形态、密度、腔内及腔外邻近组织的CT征象。结果 49例共63个囊肿,纵隔型囊肿18个,多分布在气管右旁、主支气管旁及隆突下,肺内型囊肿45个,双下肺33个,其中含液囊肿17个,含气液囊肿23个,含气囊肿5个;含液囊肿加作增强扫描,囊壁强化,囊内无强化;囊壁钙化14个,囊内容物钙化9个。结论先天性支气管肺囊肿的CT表现有一定特征性。[Objective] To investigate the manifestation of CT in congenital bronchogenic cysts.[Methods] 49 pantients（total 63 cysts）with pathologically-confirmed bronchogenic cysts were enrolled,and their site,number,size,shape,density,cystic wall,inside and the neighboring field.[Results] within 63 cysts,18 cysts were located in mediastinal,45 cysts were located lung.33 cysts in lower lobars.There are 17 liquid cysts,23 air-liquid cysts,5 air cyst.Liquid cysts were compared by nonenhancement and enhancement CT scan,walled of cyst was enhanced equally,liguid of cyst was nonenhanced.Calcification of the cystic wall was found in 14 cysts,within the cyst was found in 9 cysts.[Conclusions] The CT manifestation of congenital bronchogenic cyst are characteristic.
