摘　　要：尘肺病的特点是慢性肺部炎症和纤维化,炎症可促进肺纤维化,进而导致尘肺病。当肺内出现长径≥2 cm,短径≥1 cm的大阴影,可定为叁期尘肺病。本文对1例电子计算机断层扫描(CT)检查误诊为肺癌的右上肺大阴影伴周围毛刺样改变的叁期尘肺病患者进行分析,当尘肺病患者的大阴影病变和肺癌在CT上难以鉴别时,再行核磁共振成像(MRI)检查,特别是T2加权(T2W)成像是鉴别二者较有用的序列。Pneumoconiosis is characterized by chronic lung inflammation and fibrosis,and inflammation can promote pulmonary fibrosis,which in turn leads to pneumoconiosis.When a large shadow with a long diameter of not less than 2 cm and a short diameter of not less than 1 cm appears in the lung,it can be classified as stageⅢpneumoconiosis.This paper reports a case of stageⅢpneumoconiosis with a large shadow in the upper right lung accompanied by burr-like changes misdiagnosed as lung cancer by CT examination.When the large shadow lesions in patients with pneumoconiosis and lung cancer are difficult to distinguish on CT,an additional MRI examination,particularly T2W imaging sequence is useful sequence for identifying the two.
