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.Lipoid pneumonia presents with a variety of lung abnormalities, particularly mass forming lesions that mimic lung cancers. While 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) is expected to discriminate both diseases, some previous reports showed pseudo-positive FDG uptake in lipoid pneumonia. Here, we report a case of pathologically proven chronic lipoid pneumonia in a 78-year-old Japanese man. Computed tomography (CT) showed multi-lobar mass-forming lesions with a fat-density. PET confirmed the spotty accumulation of FDG in the corresponding fat-density area on CT, suggesting lipoid pneumonia. We reviewed the literature and discussed the FDG uptake patterns in lipoid pneumonia.A 58-year-old male patient with a bronchopleural fistula underwent endoscopic installation of an occluder at the mouth of the fistula. The fistula was located in the stump of the main bronchus of the right lung after a pulmonectomy in 2019. During medical bronchoscopy, mucopurulent contents were actively received from the mouth of the fistula. To close the fistula, the patient was simultaneously drained of the pleural cavity by Bulau and installed an occluder from an improvised tool designed for cleaning the endoscop
