“…Radiological findings in RA-ILD include ground glass-opacities, reticulation, consolidation, honeycombing, and nodules similar to other ILD subtypes [30,33,38,39]. The most common HRCT patterns in RA-ILD are UIP and NSIP, while organizing pneumonia (OP) and bronchiolitis are less common ( Figure 1) (Table 1) [8,14,[38][39][40][41][42][43][44][45][46][47]. Studies show a fairly good correlation between HRCT and histopathological findings with the least concordance in the diagnosis of UIP and NSIP [39,42,46].…”
