多层螺旋CT对外伤性肺囊肿的诊断价值

The multi-slice spiral CT diagnosis value of traumatic pulmonary psuedocysts

目的提高对外伤性肺囊肿的多层螺旋CT（MSCT）诊断认识。方法回顾性分析我院2014年1月-2015年10月28例临床和随访证实的外伤性肺囊肿的多层螺旋cT资料。结果28例中共有37个囊肿，多发囊肿7例（25％），单发囊肿21例（75％），位于上叶5个，中叶17个，下叶15个，形态上呈圆形（19例）、椭圆形（6例）或不规则形（3例）。首次MSCT检查病灶边缘均不光滑，灶周可见多少不一的渗出性病变，15例随访复查，其中13例在1周后囊肿缩小或增大。结论多层螺旋cT能清楚显示病变特征，是目前诊断外伤性肺囊肿的最佳影像学检查方法。

Objective To improve the understanding of the multi-slice spiral CT （MSCT） diagnosis of traumatic pul- monary psuedocysts. Methods The MSCT data of 28 patients with traumatic pulmonary psuedocysts proved by clinic and follow-up during Jan. 2014 to Oct. 2015 were analyzed retrospectively. Results Among the 28 cases,37 psuedo- cysts were observed,7 cases were multiple occurred （25%）,21 cases were single occurred（75%）.Of these,5 lesions were located on the upper lobe, 17 lesions were located on the middle lobe,and 15 lesions were located on the inferior lobe. The features of shape were circular（19 cases）, elliptical（6 cases） and irregular（3 cases）. The edges of lesions were all not smooth and the periphery of lesions had more or less exudation on the first MSCT examination. Among the 15 cases after a week follow-up,13 cases were reduced or disappeared in size. Conclusion MSCT can distinctly demonstrate the features of the lesions and is the optimal imaging method in the diagnosis of traumatic pulmonary psuedocysts.
