CTICasesSarcoidosis presenting as cluster-like ground-glass nodules
Imaging findings
CT scan shows clusters of tiny ground-glass nodules in a peribronchovascular distribution. A decade later, follow-up shows persistent nodularity and development of mild peribronchovascular traction bronchiectasis.
Key takeaways
Sarcoidosis can present as clustered tiny nodules that simulate ground-glass opacity on thick-slice CT. The peribronchovascular distribution and lack of lymphadenopathy are typical of this alveolar/nodular pattern.
