摘要
利用HRCT对类风湿性关节炎肺内渐进坏死性结节进行影像学诊断,指导临床治疗。回顾性分析20例经组织病理学或临床证实的类风湿性关节炎肺内渐进坏死性结节,评估其大小、位置、形态及间接征象的HRCT影像学表现特征。结果 20例患者共48个病灶大小分布于0.4cm^5.4cm之间,多分布于胸膜下,边缘不光滑;中心可伴有空洞形成;可同时伴有肺间质纤维化或难治性气胸等并发症。故类风湿性关节炎肺内渐进坏死性结节有独特的HRCT表现,充分认识并确定其特征性改变,有助于提高诊断的准确率。
b The use of HRCT in rheumatoid arthritis lung pr ogressive necrosis no dules for imaging diagnosis, to guide clinical treatment. Retrospective analysis of 20 cases of histopatho logy or clinically proven rheumatoid arthritis lung progressive necrosis no dules to assess its size, lo cat ion , shape and indirect signs of HRCT imaging characteristics. 20patientsw ere divided into 48 lesions in the range of 0. 4cm- 5. 4cm mostly distributedsmooth; the center may be associated with empty fo rmation; can also be ac companied by pulmo nary interstitial fibrosis or refractory pneumothorax and other concurrent disease. Rheumatoid arthritis lung pr ogressive necrotic no dules have aunique HRCT performance fully aware of and identify its characteristic changes , help to improv e the ac curacy of diagnosis.
