摘　　要：目的分析局灶性机化性肺炎的CT征象,提高对该病的正确诊断率。方法搜集临床资料完整并经手术及病理证实的22例病变,进行回顾性分析其影像表现。结果局灶性机化性肺炎的CT表现:①病变呈多形态广基底贴于胸膜,伴局限性胸膜粘连增厚,无胸水及钙化征象;②密度均匀或不均匀;③病灶边缘粗长毛刺;④病变周围密度较淡的模糊斑片状影,位于非胸膜侧。结论对肺部病灶形态、边缘、密度、病灶周围及胸膜改变的综合分析,能提高对本病的正确诊断率,并能与周围型肺癌,结核瘤作出鉴别诊断,减少误诊。Objective To improve the correct rate of focal organizing pneumonia＇s diagnosis by analyzing the CT signs. Methods The clinical data of 22 cases confirmed by surgery and pathology were collected and analyzed retrospectively. Results The CT features of focal organizing pneumonia were： （1） The lesion was irregular shape, and broad-base lesions often affixed to the pleura with adjacent pleural thickening. （2）Density was uniform or non-uniform. （3）Lesions edge was coarse spicule. （4）The satellite lesion with lighter density located in the lateral pleura. Conclusions The comprehensive and intergraded analysis of the lesion, edge, density, change of pleura of lung involvement can improve the accurate rate of imaging diagnosis in focal organizing pneumonia, differentiate with peripheral lung cancer and tuberculosis, and reduce misdiagnosis.
