Case report demonstrates an atypical basal-predominant phenotype of pulmonary sarcoidosis mimicking pulmonary fibrosis in a young female, highlighting diagnostic challenges in atypical presentations.
Pulmonary sarcoidosis is a systemic inflammatory disease characterized by the formation of non‐caseating granulomas; it typically presents with bilateral hilar lymphadenopathy and upper‐lobe predominant interstitial infiltrates. However, atypical radiological presentations can mimic fibrotic interstitial lung diseases, posing a significant diagnostic challenge. We present a case of pulmonary sarcoidosis in a young female who had a confounding basal‐peripheral phenotype, eventually diagnosed through endobronchial biopsy showing non‐necrotizing granulomas with asteroid bodies.
