中央型肺癌的X线与CT诊断(附21例分析)

Diagnosis of Central pulmonary carcinoma with X- ray and CT: a preliminary a nalysis of 21 cases

目的分析中央型肺癌的X线与CT表现并比较这两种方法的诊断能力。方法21例经纤维支气管镜或病理证实的中央型肺癌患者均经胸部X线与CT检查。对全部病例的X线与CT表现进行了回顾性分析。结果在胸部X线与CT像上,中央型肺癌均表现为肺门肿块合并阻塞性肺炎和肺不张。此外,CT还显示了X线胸片未看到的支气管壁增厚和管腔变窄,以及纵隔淋巴结肿大等。结论X线与CT是诊断中央型肺癌的主要方法,而CT的诊断能力明显优于X线平片。

Objective To analyze the X- ray and CT findings of ce nt ral pulmonary carcinoma and to compare the diagnostic capacity of X- ray and CT .Methods Twenty- one patients with central pulmonary carcinoma which was confir med by fibrobronchoscopy or pathology underwent X- ray and CT examinations of t he chest.X- ray and CT findings in all patients were retrospectively analyzed.R esults On X- ray and CT images of the chest,central pulmonary carcinoma appeare d as pulmonary- porta masses or associated with obstructive pneumonia,atelectas is,in addition to these,CT also revealed thickened bronchial walls,narrowing bro nchial lumen and mediastinal lymphonode enlargement not visible on plain roentge nograms.Conclusion X- ray and CT are main methods for diagnosing central pulmon ary carcinoma,while the diagnostic capacity of CT is obviously superior to that of X- ray plain film.
