CTICasesEvolution of rheumatoid arthritis-associated ILD (RA-ILD)
Imaging findings
Serial CT scans over 9 years show progression of RA-ILD from a mild, peripheral, lower-lobe predominant ground-glass and reticular pattern (NSIP-like) to advanced subpleural honeycombing and traction bronchiectasis (UIP-like).
Key takeaways
RA-ILD can histologically and radiographically evolve over time. An initial NSIP-like pattern can progress to a classic UIP-like pattern with honeycombing, reflecting progressive fibrotic remodeling.
