摘　　要：目的:探讨纵隔纤维化的CT临床表现特征。方法:回顾性分析经临床确诊的9例纵隔纤维化患者胸部CT影像资料,分别就病变形态、受累范围、是否伴有肿块、钙化、气道狭窄、肺动脉高压以及肺不张等临床表现进行总结。结果:CT表现为纵隔内脂肪密度消失,被软组织影代替;不定型软组织密度影,多围绕支气管血管束分布(束管征);伴或不伴淋巴结肿大、钙化;继发多叶段的支气管及肺动脉狭窄,并发肺不张及肺动脉高压。结论:纵隔纤维化有一定的表现特征,CT检查可以做出定性诊断,但需要和侵袭性胸腺瘤或胸腺癌、纵隔淋巴瘤、结节病、支气管内膜结核等进行鉴别。Objective:To explore the CT clinical manifestations of mediastinal fibrosis.Methods:The chest CT imaging data of 9 clinically diagnosed patients with mediastinal fibrosis were retrospectively analyzed,The morphology of the lesion,the extent of involvement,whether accompanied by mass,calcification,airway stenosis,pulmonary hypertension and atelectasis were summarized.Results:CT showed that fat density disappeared in mediastinum and was replaced by soft tissue shadow;atypical soft tissue density shadow,mostly distributed around the bronchial vascular bundle(bundle sign);with or without lymph node enlargement and calcification;secondary bronchial and pulmonary artery stenosis,atelectasis and pulmonary hypertension.Conclusion:Mediastinal fibrosis has certain characteristics.CT examination can make qualitative diagnosis,but it needs to be differentiated from invasive thymoma or thymic cancer,mediastinal lymphoma,sarcoidosis,endobronchial tuberculosis,etc.
