2例肺炎性假瘤的X线及CT影像学特点分析

Imaging feature of X-ray and CT in 2 cases of lung inflammatory pseudotumor

目的研究肺炎性假瘤的X线及CT影像学特点,提高其诊断及鉴别诊断水平。方法分析2例手术病理证实的肺炎性假瘤患者的X线及CT资料,结合文献复习,评价其影像表现的诊断意义。结果2例肺炎性假瘤均位于右下肺,邻近肺边缘。1例边缘毛糙,1例初诊边缘光整,后期毛糙。2例均有邻近胸膜增厚,并可见平直征。结论对发生于右肺,尤其是下叶邻近胸膜部的占位性病变,出现桃尖征、平直征及胸膜带状增厚征均应注意与肺炎性假瘤鉴别,而不要过分强调肺癌的可能性。

Objective To investigate the X-ray and CT imaging characters of inflammatory pseudotumor of the lung（IPL） for improving the ability of diagnosis and differential diagnosis. Methods X-ray and CT imaging of two cases of IPL,proved by surgical pathology,combined with document materials, were analysed for its diagnostic significance. Results Two cases of IPL were located at the right low lung,near the lung margine. One case had rough surface; another case had smooth surface at first, then became rough; two cases both had nearby incrassate pleura. Conclusion The right lung mass,especially close to low pleura, possibly with pleura incrassation, should be thought firstly as IPL,but the possibility of lung cancer should not be overemphasized.
