目的 :总结球形肺炎的 CT特征 ,提高 CT诊断水平。方法 :收集经临床证实的 2 0例球形肺炎的 CT资料进行回顾分析。结果 :主要 CT表现为贴近胸膜呈方形或三角形 :边缘不规则 ,模糊 ,浅分叶 ;中央密度较外周高 ,可见“晕征”,增强扫描内见界面规则、清晰的低密度区 ;病灶与胸膜接触面广 ,可见胸膜外透亮线 ;可见较明显的支气管充气征 ,腔略扩张 ,管壁规则 :非胸膜侧伴有炎性渗出灶 ;病灶周围有增多、增粗、扭曲的充血血管 ;抗炎治疗后复查病灶吸收缩小、消失。结论 :上述 CT征象有一定的特征性 ,结合临床资料有助于诊断球形肺炎和与周围型肺癌鉴别
Objective: To summarize the CT features of spherical pneumonia and improve the diagnostic value of CT. Methods: CT data of 20 cases of spherical pneumonia clinically confirmed were retrospectively analyzed. Results: The main CT showed pleural square or triangle: the edge of the irregular, fuzzy, shallow lobes; central density higher than the outer circumference, visible “halo sign”, enhanced scan interface rules, clear low density area; lesions and Pleural contact area is broad, visible extrapleural transparent line; visible more obvious signs of bronchial inflatable, slightly dilated cavity wall rules: non-pleural side accompanied by inflammatory exudative lesions; lesions around increased, thickening, distorted blood vessels After anti-inflammatory treatment, the lesions recovered and disappeared. Conclusion: The CT signs have certain characteristics, combined with clinical data to help diagnose spherical pneumonia and peripheral lung cancer
