胸部结节病的CT表现

目的 探讨CT在胸部结节病诊断和鉴别诊断中的价值。方法 回顾性分析18例胸部结节病患者的CT检查资料。5例经纤支镜活检病理证实，13例经临床随访治愈确诊。结果 15例病变累及肺门或／和纵隔淋巴结。增大的肺门淋巴结呈两倒对称性，纵隔淋巴结呈广泛分布。增大淋巴结密度均匀，边界清楚，无浸润性改变，增强扫描呈中度均匀性强化。另3例呈肺间质纤维化改变。结论 CT扫描是胸部结节病诊断和鉴别诊断有效的方法，并能观察病变的变化，指导临床治疗。

CT findings in thoracic sarcoidosis

Objective To evaluate role of CT in (differential) diagnosis of thoracic sarcoidosis. Methods A review of CT images of 25 cases of thoracic sarcoidosis was conducted.Five cases were confirmed infectious granuloma,and 13 cases were cured during follow-up. Results Fifteen cases involved lymph nodes in hilus of lung and/or mediastinum. Enlarged lymph nodes in hilus were symmetric and in mediastinum were universal.The enlarged lymph nodes were even in density with sharp demarcation free from infiltration,displaying an even enhancement in enhanced scan.Three cases had pulmonary interstitial fibrosis. Conclusion It is concluded that CT scan plays an effective role in(differential) diagnosis of thoracic sarcoidosis,as well as in observing evolution and guiding therapy.
