气管支气管内炎性假瘤X线与CT诊断

目的探讨气管支气管内炎性假瘤X线与CT诊断，提高诊断水平。方法搜集1例证实为支气管内炎性假瘤的病例，复习近几年来国内外气管支气管内炎性假瘤的影像表现，讨论其X线、CT特征、诊断及鉴别诊断。结果气管支气管内炎性假瘤的胸片表现为气管内或支气管内结节或孤立的肺内肿块，有的伴或不伴阻塞性肺炎或肺不张。CT为结节状或类圆形肿块，常伴阻塞性肺炎或肺不张，注射造影剂后肿块呈较明显均匀或不均匀强化。结论气管支气管内炎性假瘤的X线及CT表现缺乏特征性，容易与其他气管支气管内肿瘤混淆，但结合临床资料可以诊断。

X-ray and CT Findings of Intrabronchial Inflammatory Pseudotumor

Objective To evaluate the value of IBIPT in X-ray and CT. Methods X-ray and CT images of one case which was proved by pathology were studied with the literaturereviews. Results On posteroanterior chest radiography, the tumors were seen as a endotracheal or endobronchial nodule, a solitary pulmonary nodule or mass, a mass with obstructive pneumonia or atelectasis. The nodules were smoothly oval, some with postobstructive pneumoniaor atelectasis. Inflammatory pseudotumor shows mild enhancement after the administration of the contrast medium. Conclusion Bronchial inflammatory pseudotumor has rarely special changes in CT images. It always be confused with other bronchial tumor. Combined with clinical data, CT can be helpful to diagnose bronchial inflammatory pseudotumor.
