CTICasesCavitating Pulmonary Rheumatoid Nodules
Imaging findings
Chest radiograph and CT show multiple pulmonary nodules distributed along the pleura and fissures. Over a five-to-six-year period, these nodules demonstrate varying degrees of cavitation, growth, and resolution. Destructive arthritic changes are also visible in the shoulders on the chest radiograph.
Key takeaways
Rheumatoid nodules are a well-recognized extra-articular manifestation of rheumatoid arthritis. They typically locate peripherally, often along the pleura or fissures, and can characteristically cavitate, wax, and wane over time. While benign, they can sometimes lead to complications such as pneumothorax or bronchopleural fistula.
