Greasy lung

A 62-year-old retired fire performer came to the emergency department complaining of persistent cough, difficulty breathing, and unintentional weight loss over the last two months. He also mentioned a history of occasional fever but denies night sweats and has not travelled outside of Canada. He shared his past as a fire performer, often swallowing and blowing fire using petroleum-based fuels. He has a 20-pack-year history of smoking and was diagnosed with COPD 5 years ago. On examination, the patient was observed to be in mild respiratory distress with an oxygen saturation of 92% on room air, and auscultation revealed decreased breath sounds in the right lower lung field. Chest radiograph showed a right lower lobe consolidation, as shown in the image, and a high-resolution CT scan revealed diffuse ground-glass opacities in both lungs with areas of consolidation in the right lower lobe. Lab results revealed an elevated white blood cell count and C-reactive protein level. The bronchoscopy showed nothing unusual; culture for acid-fast bacilli and fungi came back negative, with the cytology only highlighting the presence of foamy macrophages.
