CTICasesSarcoidosis with Pseudo-Plaque Pattern
Imaging findings
CT shows classic hilar and mediastinal adenopathy characteristic of sarcoidosis, along with a pronounced peripheral, directly subpleural consolidation presenting as a "pseudo-plaque" pattern. These pseudo-plaques appear as solid blocks of conglomerated consolidation, rather than typical micro-nodularity. Post-treatment with steroids, the adenopathy and pseudo-plaques significantly improved.
Key takeaways
Sarcoidosis has diverse manifestations, including an unusual "pseudo-plaque" pattern of peripheral subpleural consolidation. This pattern, though less common, can be a feature of sarcoidosis and typically responds well to steroid treatment, along with the more classic lymphadenopathy.
