右上纵隔增宽的CT诊断价值(附56例分析)

目的探讨X线平片右上纵隔增宽的CT诊断价值。方法分析56例经手术、病理或CT增强扫描、心脏超声证实的右上纵隔增宽X线和CT表现。所有病例均行X线平片和CT平扫,其中51例行CT增强扫描。结果非侵袭性胸腺瘤6例;侵袭性胸腺瘤致上腔静脉综合征2例;胸内甲状腺肿瘤2例;升主动脉或无名动脉迂曲14例;胸主动脉瘤3例;肺动脉狭窄致主肺动脉扩张1例;右位主动脉弓2例;淋巴瘤4例;右肺纵隔型肺癌16例;隐匿型肺癌2例;食管下段癌致胸上段食管明显扩张2例;食管异物继发上纵隔脓肿2例。经CT平扫 增强扫描、手术、病理、心脏超声证实病例数分别为33、10、12、1例。结论CT扫描是诊断右上纵隔增宽的可靠检查方法。

The Value of CT Diagnosis in Broadening of Right Upper Mediastinum: An Analysis of 56 Cases

Objective To explore the value of CT diagnosis in broadening of right upper mediastinum.Methods X-ray plain film and CT manifestations of broadening of right upper mediastinum in 56 cases proved by surgery and pathology or CT enhancement or heart ultrasound were analyzed. 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.
