CTICasesCavitating Rheumatoid Lung Nodules
Imaging findings
CT chest shows multiple well-circumscribed, subpleural nodules in both lungs, some of which demonstrate central cavitation with smooth inner walls. The patient has a long-standing history of rheumatoid arthritis and is asymptomatic.
Key takeaways
Rheumatoid nodules are a common non-metabolic manifestation of rheumatoid arthritis. They typically locate subpleurally, can vary in size, and frequently undergo cavitation. Cavitating nodules can mimic malignancy or infection (such as TB or fungal disease), but their subpleural distribution and clinical history are highly suggestive.
