摘要
目的 分析慢性肺段肺炎的X线与CT特点及诊断价值。方法 搜集 2 2例慢性肺段肺炎。全部经穿刺、手术病理 ,或临床随访证实。重点观察病灶的外形、边缘、密度、支气管和邻近改变。结果 大多数肺段病灶平片呈尖朝向肺门 ,底部位于肺外周的楔形片状或片块状阴影。CT则为 2～ 3个以上的层面呈楔形或锥状 ,少数病灶需将各个层面叠加起来方呈锥形外观。慢性肺段肺炎病灶边缘多稍内凹或平直 ,楔尖支气管通畅 ,未见结节 ;密度较均匀 ,可见支气管气像或支扩 ;底部相邻胸膜增厚明显。X线和CT诊断符合率分别为 6 3 6 %和 77 3%。结论 慢性肺段肺炎的影像表现有一定特点 ,诊断时须综合分析各种征象。
Objective To analyze the X-ray and CT features of the chronic pulmonary lescons pneumonitis.Methods The CT findings of 22 patients with chronic pulmonary lescons pneumonit were reviewed.The diagnosises were proved by pathologically.Results Wedge-shape or cone-shape of lesions were demonstrated in most of cases.In these chronic pneumonitis cases,the borders of lesions were depressire or straight without hilar mass and obstructed bronchus.Most lesions were isodensity and the air bronchogram could be found in some cases.According to the above,63.6% and 77.3% of the cases were diagnosed correctly.Conclusions Some relative specific CT manifestations mere existed in the chronic pulmonary lescons pneumonitis.But the CT findings of some patients were similar to each other.
