CT WITH SUBPLEURAL AND LYMPHOVASCULAR NODULES IN THE RIGHT UPPER LOBE – INTERLOBULAR SEPTA AND CENTRILOBULAR SARCOIDOSIS, ACTIVE – ALVEOLAR FORM 48-year-old previously well presented with dyspnea and initial CXR showed an infiltrate at the right base, and clinically resolved. He presented a year later with right chest pain and low grade ever and the CXR showed patchy opacities in the LUL and in the RLL A subsequent CT showed LUL nodular opacities and subpleural rim of consolidation in the LUL and more prominently at both lung bases, associated with significant mediastinal adenopathy. Lymphovacscular nodularity was noted in the bronchovascular bundles as well as in the interlobular septa, consistent with sarcoidosis CXR and CT 4 years later showed almost complete resolution of the parenchymal findings and the CT findings except for minimal reticulation and scarring in the subpleural regions Ashley Davidoff MD
