Sarcoidosis Presenting As A Solitary Pulmonary Mass

Sarcoidosis has a wide varying presentation. Pulmonary sarcoidosis typically presents with bilateral hilar adenopathy and reticulonodular opacities. Very rarely it can present as a single solitary mass. Here we present a case of a 39 year old African-American male who presented with cough and pleuritic chest pain. Initial imaging revealed a right lower lobe airspace opacity, concerning for pneumonia. Despite treatment with antibiotics, symptoms and radiological findings persisted. A PET scan revealed a FDG positive right lower lobe pulmonary mass. Biopsy of the mass and lymph nodes revealed non-caseating granulomas suggestive of sarcoidosis. This case showcases a rare presentation of pulmonary nodular sarcoidosis.
