Atypical sarcoidosis: About a case

Chronic lung consolidation is often associated with various respiratory pathologies, ranging from chronic infections to interstitial diseases such as sarcoidosis, which is a benign systemic granulomatosis of unknown etiology. Interstitial parenchymal involvement is usual. The pseudo-alveolar form is atypical, often presenting acutely, difficult to diagnose, but tends to evolve rapidly favorably under corticosteroid therapy. We report here a case of pseudo-alveolar sarcoidosis in a 58-year-old patient whose radiological and clinical presentation is unique and perplexing. In this study, we emphasize the rarity of this pseudo-alveolar sarcoidosis.
