目的探讨结节和肿块型局灶性机化性肺炎(FNMOP)临床和CT特征,以提高与肺癌的鉴别诊断水平。方法搜集经病理证实的14例NMFOP患者的临床资料、实验室检查(肿瘤标记物和D-二聚体)及CT影像资料,并对这些资料进行回顾性总结分析。结果 14例患者中,病灶为圆形或类圆形者5例,不规则形9例;边缘清晰5例,病灶边缘模糊9例;浅分叶7例,深分叶3例;短毛刺1例,长毛刺2例;3例有血管集束征,8例有棘突征。右肺9例,肺上叶9例。结论结合临床资料、肿瘤标记物和D-二聚体及CT特征进行综合分析,有助于对FNMOP的鉴别诊断。
Objective To investigate the clinical and CT features of nodular and tumor-localized focal pneumonitis (FNMOP) in order to improve the differential diagnosis of lung cancer. Methods The clinical data, laboratory tests (tumor markers and D-dimers) and CT images of 14 NMFOP patients confirmed by pathology were collected. The data were retrospectively analyzed. Results Among the 14 patients, the lesions were round or oval in 5 cases and irregular in 9 cases. The margins were clear in 5 cases and the margin was fuzzy in 9 cases. The superficial lobes were 7 and the deep lobes were 3. Cases, long burr in 2 cases; 3 cases of vascular bundles signs, 8 cases of spinous processes. Right lung in 9 cases, 9 cases of upper lobe. Conclusion Combined clinical data, tumor markers and D-dimer and CT characteristics of a comprehensive analysis, contribute to the differential diagnosis of FNMOP.
