摘要
目的分析运用螺旋CT对局灶性机化性肺炎与周围型肺癌的鉴别诊断。方法采用回顾性方法,选取我院自2012年5月-2013年10月收治的40例局灶性机化性肺炎患者作为观察组;同时选取同期我院收治的40例周围型肺癌患者作为对照组,比较两组螺旋CT影像特征。结果观察组患者棘状突出征、弓形凹陷征、深分叶征、支气管充气征、长短毛刺征、邻近胸膜增厚、液化和坏死、钙化以及淋巴结肿大出现病例数与对照组差异明显(P<0.05),其他症状差异比较无统计学意(P>0.05);观察组增强CT增加平均值大于对照组(P<0.05),且观察组患者病灶部位多居于右肺上(87.5%),其病灶形态多为类圆形(47.5%),边缘清楚者占大多数(62.50%)。结论局灶性机化性肺炎在影像学上具有一定的特点,这些特点可通过螺旋CT显示出,有利于帮助与周围肺癌的鉴别诊断。
Objective To analyze the use of spiral CT in the differential diagnosis of focal organizing pneumonia and peripheral lung cancer.Methods Methods： using the retrospective method, selects my courtyard from 2012 May -2013 year in October admitted 40 cases of focal organizing pneumonia patients as the observation group; at the same time, a total of 40 cases of peripheral lung cancer patients in our hospital as control group, compared two groups of spiral CT imaging features.Results The patients in the observation group spinous herniation, bow indentation sign, deep lobulation sign, air bronchogram, short spiculation, adjacent pleural thickening, liquefaction and necrosis, calcification and the lymph nodes the number of cases and control group had obvious difference（P〈0.05）, no significant differences compared to other symptoms （P〉0.05）; enhanced CT increase of mean value is greater than the control group （P〈0.05）, and the observation group patients the lesion site resides in the right upper lung （87.5%）, the lesions were oval in shape （47.5%）, the edge of a clear majority （62.50%）.Conclusion Focal organizing pneumonia in imaging has certain features which can be shown by spiral CT, is conducive to the differential diagnosis to help with the surrounding lung cancer.
