中央型肺类癌临床X线及CT表现

Manifestation of clinical, X-ray and CT in central lung carcinoid tumor

目的:探讨中央型肺类癌临床、X线与CT表现特点。方法:回顾性分析经手术病理证实的21例中央型肺类癌临床、X线及CT表现。结果:临床主要表现为咳嗽20例,痰中带血丝或咯血8例,胸闷11例,胸痛6例,发热12例。胸部平片肿瘤位于右肺14例,左肺7例;阻塞性炎症13例,肺不张5例。12例经CT扫描,支气管狭窄伴肺门区肿块12例,CT增强扫描肿瘤呈轻中度强化。结论:中央型肺类癌影像学缺乏特征性,X线与CT表现仅能提示诊断,术前确诊需经支气管内窥镜活检或经皮肺穿活检。

Objective To study the clinical, X-ray and CT features of central lung carcinoid tumor. Methods Twenty-one cases of central lung carcinoid tumor were confirmed by surgery and pathology. The findings on X-ray and CT in 21 cases were retrospectively analyzed. Results The clinical manifestations were cough in 20 cases, hemoptysis in 8 cases, chest distress in 11 cases, thoracodynia in 6 cases and fever in 12 cases. The chest plain film showed lesions of right lung in 14 cases, and lesions of left lung in 7 cases. 13 cases of obstructive pneumonia and 5 cases of atelectasis were found. CT showed 12 cases of bronchiostenosis with lesions in hilum of lung. The CT value of the lesions was enhanced up. Conclusion Central lung carcinoid tumor is lack of typical imaging manifestations. Imaging manifestation of X-ray and CT only has a clue to diagnosis. The definite diagnosis needs bronchoscopic biopsy and percutaneous pulmonal puncture biopsy.
