摘要
目的通过对球形肺炎的CT征象进行回顾性分析,探讨其误诊的原因。方法收集30例经手术及临床证实的球形肺炎患者的CT资料,分析其CT征象。结果球形肺炎的主要CT表现包括:①病变两侧缘垂直于胸膜呈刀切样平直边缘;②病变中央密度高,边缘密度低,显示晕圈状改变;③病变边缘有锯齿状改变但较模糊;④周围胸膜反应显著;⑤病变周围血管纹理增多、增粗;⑥抗炎治疗后病变明显吸收。结论球形肺炎误诊率较高。认真分析CT影像征象,结合临床资料,并进行动态观察,可提高诊断准确率。
Objective To explore the reasons for its misdiagnosis through retrospective analysis the CT signs of spherical pneumonia.Methods Collected the CT and X-ray data of 30 cases with spherical pneumonia diagnosed by surgery and clinical,and analyzed the CT features of them.Results The main CT features were as follows：①Bilateral margins of the lesion were perpendicular to pleura with straight cut edge presenting a knife-like straight-edge sign.②The density at the margin of the lesion was lower than that at the central area,sometimes presenting a halo-like appearance.③Irregular or spiculate margins with illdefined outline could be seen.④There was extensive pleural thickening involving interlobar fissure as the response to inflammation.⑤There were small patches slightly high density and/or intensified vascular markings surrounding the lesions.⑥After short-term anti-inflammatory therapy,most lesions were obviously reduced in size.Conclusion The rate of misdiagnosis of spherical pneumonia is high.Analyze the CT signs carefully,combined with clinical data,and dynamic observation could improve the diagnostic accuracy.
