摘　　要：目的通过分析外伤性肺囊肿多层螺旋CT(MSCT)的影像特点,以探讨其对外伤性肺囊肿的诊断价值。方法回顾性分析20例外伤性肺囊肿患者CT表现,包括常规扫描、横轴面薄层重组和冠状面、矢状面多平面重组图像。结果 20例外伤性肺囊肿共有囊肿26个,单发15例(占75%),多发5例(占25%)。CT表现为肺气囊肿3个(11.5%),气液囊肿15个(57.7%),液性囊肿8个(30.8%),三型囊肿可以相互转化。多平面重组图像显示囊肿数目、形态更清晰(P=0.01)。结论 MSCT检查是早期发现、诊断、分型及动态观察外伤性肺囊肿的最佳方法,对临床诊断及治疗具有重要指导价值。Objective To study multi-slice spiral computed tomograghy（MSCT） features in traumatic cyst of lung and to discuss the diagnostic value of MSCT in this kind of disease.Methods The pulmonary imaging data of 20 cases with pulmonary traumatic cyst,which were performed with MSCT,including conventional slice thickness,axial thin section and coronal,sagittal multi planar reconstruction（MPR） images,were retrospectively analyzed.Results There were 26 cysts in 20 cases of traumatic lung cyst,with solitary cyst in 15 cases（75%） and multiple cysts in 5 cases（25%）.The CT findings included pulmonary air filled cysts in 3 cases（11.5%）,fluid and air filled cysts in 15 cases（57.7%）,fluid filled cysts in 8 cases,（30.8%）.These three types of cyst can be transformed into each other.MPR image showed the number and form of cysts more clearly.Conclusion MSCT is the technique of choice in early detection,diagnosis and follow-up of Traumatic Cyst of Lung,which plays an important role in the guidance of treatment planning.
