title: [A case of sarcoidosis presenting as a solitary pulmonary nodule].
abstract: A 73-year-old woman presented at a private clinic because of non productive cough. She was treated with several drugs, but no relief was obtained. She was therefore referred to our hospital for further investigations. Chest CT films revealed a solitary nodule in the right lower lung field and mediastinal and bilateral hilar lymphadenopathy. The FDG-PET CT showed a high FDG uptake in the pulmonary nodule and bilateral hilar and mediastinal lymph nodes. Her serum angiotensin-converting enzyme level was normal and a PPD skin test was negative. Because the transbronchial biopsy specimens were not diagnostic, video-assisted thoracoscopic surgery was performed. The pathologic diagnosis of the resected lung and lymph node was sarcoidosis. There was no sign of other organ involvement. The symptoms remitted without steroid therapy and one year after surgery she continues to do well and has no evidence of recurrence.
