11例原发性气管恶性肿瘤的临床X线分析

The Clinical and Radiographic Analysis on Primary Trachea Malignant Tumor in 11 Cases

原发性气管恶性肿瘤早期诊断困难,由于无典型症状,本病常误诊,一旦确诊,多属晚期,治疗效果不理想。临床上常表现为间歇性刺激性咳嗽,渐进性呼吸困难,痰中带血、气促、声嘶等。常规X线全胸正侧位片肺门纵隔无明显异常,未能提示有纵隔气管肿瘤的X线征。部分可见肺炎或节段性肺不张。气管分叉断层片可显示气管内有软组织肿物。最后需作支气管纤维镜病理活检确诊。

Early diagnosis of primary trachea malignant tumor was difficult. This disease was usually misdiagnosed, because of few typical symptoms. Most of these cases were in late stage when diagnosis was made. So that the treatment effect was unsatisfactory. Clinically, it usually presented intermittent irratitatced cough, progressive dyspnea, cough with blood, panting, hoarseness, etc. Conventional chest radiogram showed normal hila and mediastinum and couldn't indicate radiographic sign of tracheal and mediastinal tumor. Pneumonia and segmental atelectasis may be seen in some cases. Tomogram may reveal intratracheal soft tissue mass in some cases. Pathological biopsy must be made for diagnosing the disease by bronchoscopy.
