High-resolution CT showed areas of airspace consolidation with a twisted appearance of the airways, along with areas of peribronchial ground-glass attenuation and traction bronchiectasis, in five patients with interstitial pneumonia. These areas of airspace consolidation were termed "twisted consolidation" (TwC). The five patients included two patients receiving treatment for rheumatoid arthritis (RA), one patient with newly diagnosed RA, and one patient who subsequently showed RA. Three patients showed improvement after steroid administration. An association of TwC with RA is suspected, but further studies are necessary.
高分辨率CT显示，5例间质性肺炎患者出现气腔实变区域，气道呈扭曲状，同时伴有支气管周围磨玻璃样衰减区域和牵拉性支气管扩张。这些气腔实变区域被称为“扭曲实变”（TwC）。这5例患者中，2例正在接受类风湿关节炎（RA）治疗，1例为新诊断的RA患者，1例随后出现RA。3例患者在使用类固醇药物后病情有所改善。怀疑TwC与RA有关，但还需要进一步研究。
