摘要
目的明确结节病累及纵隔淋巴结的增强多层螺旋CT(MDCT)强化特征及解剖分布,提高对结节病的诊断准确性。方法收集经病理或临床证实的39例结节病增强MDCT表现,回顾性分析增大纵隔淋巴结大小、形态、强化特征及解剖分布。结果 39例病例中,33例(85%)增大淋巴结呈均匀强化,6例(15%)呈均匀强化合并环形强化;增大淋巴结常优势累及纵隔10R区(37例,95%),10L区(35例,90%),2R区(27例,69%),7区(27例,69%),5区(23例,58%)。结论增强MDCT能显示增大纵隔淋巴结强化特征及优势解剖分布,有助于对结节病的诊断。
Objective To determine the enhancement patterns and anatomic distribution of enlarged mediastinal lymph nodes using contrast-enhanced multi-detector CT （MDCT） in patients with sarcoidosis. Methods We reviewed the contrast-enhanced MDCT features of 39 patients with pathologically or clinically diagnosed sarcoidosis, including the size, morphology, attenuation, enhancement patterns, and anatomic distribution of the enlarged mediastinal lymph nodes. Results Of the 39 patients, 85% showed homogenous enhancement and 15% showed homogenous mixed with peripheral enhancement. The enlarged lymph nodes were predominantly distributed in the regions of 10R （95~）, 10L （90~）, 2R （69~）, 7 （69~）, and 5 （58~）. Conclusion Contrast-enhanced MDCT can detect the enhancement patterns and predominant anatomic distribution of enlarged mediastinal lymph nodes, which is of great value for the diagnosis of sarcoidosis.
