Figure 1 (A) Chest CT showing a mass-like consolidation surrounded by ground-glass opacities in the posterior segment of the right upper lobe designated B2. (B) Significant uptake (SUV, 11.62) of F18-fluorodeoxyglucose (FDG) by the lipoid pneumonia is seen on positron emission tomography (PET). (C) Moderate uptake (SUV, 2.78) of F18-fluorodeoxythymidine (FLT) is seen on PET.

Figure 2 (A) Bronchoalveolar lavage fluid images showing that intracytoplasmic substances in alveolar macrophages are positive for Sudan III staining (main image, 40×; inset, 100×). (B) Numerous foamy macrophages and lymphocytes (arrow) are seen in alveolar spaces in a transbronchial lung specimen (HE stain, 40×).
