摘要
目的 分析引起右上纵隔增宽的各种病变的影像学表现特点，以利于鉴别诊断。材料与方法 胸片上显示右上纵隔增宽５１例，年龄２０～８０岁；男３１例，女２０例。摄有正、侧位胸片，部分病人做了ＣＴ扫描。另外，任意挑选２５０例５０岁以上有正、侧位胸片者，对右上纵隔宽度作出测量。根据增宽程度，作出分度。结果 右上纵隔增宽气管无移位时，常见有无名动脉扭曲、纵隔型肺癌、右上包裹性积液等，气管移位见有甲状腺良恶性肿瘤、右位主动脉弓、右下叶不张等。结论 右上纵隔增宽，先应注意正位胸片气管有无移位，再根据其他Ｘ线征象并结合侧位片、透视及高仟伏摄影仔细分析，大多数病变都可以作出正确定位与定性，较为复杂的病例可进一步作ＣＴ检查。
Purpose imaging findings of the lesions which cause right upper mediastinum widening were analysed for differential diagnosis. Materials and Methods Fifty - one patients with broadened right upper mediastinum on chest radio- graphies (aged 20 - 80 years; 31 males and 20 females) underwent posterior - anterior(P - A) and lateral projection, some of them underwent additional CT scan. In addition, 250 cases over 50 years old were arbitrarily selected with P - A and lateral chest films. The breadth of upper right mediastium in these persons were measured, degrees were divided according to varied widenings. Results When the right upper mediastinum were broadened without displacing of trachea, buckling of the innominate artery, mediastinum type of lung cancer, right upper encysted pleurisy and so on were often seen, when with the trachea of displacement, thyroid tumors, right aortic arch, right lower lobe atelectasis and others were frequently noticed. Conclusion Whether the trachea was displaced or not should be pay attention to first in broadening of the right upper mediastinum, then other X - ray signs combining lateral film, fluoroscopy and high voltage film should be determined care- fully. The most of the lesions would be made located diagnosis and qualitative diagnosis, complex conditions might be performed CT scanning for further differentiation.
