先天性支气管肺囊肿的多层螺旋CT表现

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。

Imaging Findings of Multi-slice Spiral CT of Congenital Bronchopulmonary Cyst

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 ...
