All cases were undergone radiography and CT scan. The contrast-enhanced CT scans were carried out in 51 cases.Results The study showed:un-invasive thymoma in 6 cases,invasive thymoma resulted in superior vena cava syndrome in 2 cases,intrathoracic thyroid tumors in 2 cases,ascending aorta or innominate artery dilatation in 14 cases,thoracic aortic aneurysm in 3 cases,pulmonary artery stenosis resulted in aortopulmonary dilatation in 1 cases,right sided aorta in 2 cases,lymphoma in 4 cases,the right mediastinal lung carcinoma in 16 cases,larvate focus of lung carcinoma in 2 cases,low esophageal carcinoma resulted in upper esophagectasia in 2 cases,foreign body of esophageal secondary upper mediastinal abscess in 2 cases. The cases proved by plain and contrast-enhanced CT scan,operation,pathology and heart ultrasound were 33,10,12 and 1 cases respectively. Conclusion CT scan is a effective method in the diagnosis of broadening of right upper mediastinum.
