摘　　要：目的:探讨支气管肺囊肿CT表现及应用价值。方法:回顾分析经手术病理证实的27例支气管肺囊肿的影像学表现。27例中男18例,女9例,年龄2天～13岁,平均2.6岁。27例均行X线检查及CT平扫,其中12例行CT增强扫描和/或重组,包括多平面重组(MPR)、容积再现(VR)。结果:27例中22例位于肺内,5例位于纵隔内。5例纵隔内囊肿均为单发囊性病变,液性密度;22例肺内囊肿14例为气性,7例为气液性,1例为液性,2例为气液性囊肿内有明显气液平面。囊肿直径从1cm到10cm。其中7例肺囊肿周围合并感染灶。增强扫描囊壁略有强化。MPR及VR图像可以清晰显示囊肿的位置及与气管、邻近器官的关系。结论:支气管肺囊肿可发生于气管支气管树的任何部位,CT扫描特别是CT重组能更好显示病变及与支气管、周围器官的关系。Objective：To study the appearances of congenital bronchopulmonary cysts presented by multislice spiral CT （MSCT） with volume rendering （VR） and multiplanar reconstruction （MPR）. Methods： The clinical data of 27 cases （18 boys, 9 girls,age range 2 days to 13 years, average age 2.6 years） with congenital bronchopulmonary cysts proved by operation and pathology were reviewed retrospectively. All cases underwent non-enhanced CT scan and 12 of them received enhanced CT scan with VR and MPR reconstruction. Results：The cysts of 22 out of 27 cases were located in the lung and the lesions showed pure gas density in 14 cases,mixed gas and liquid density in 7 cases including air-liquid level in 2 cases, and 1 case was revealed pure liquid density. The lesions located in the mediastinum presented single cystic lesion in 5 cases. The diameters of cysts were from lcm to 10cm; there were cystic lesions with surrounding infection in 7 cases. The cyst wall was enhanced slightly in 7 cases. MPR and VR reconstruction clearly showed the locations of cysts and their relation to the bronchus or other organs. Conclusion： Since bronchopulmonary cyst can originate from any place of trachea and bronchus tree, CT scan, especially with VR and MPR reconstruction, can provide accurate evaluation for bronchopulmonary cysts and their relationship with the bronchus and adjacent organs.
