Exogenous Lipoid Pneumonia

A 38-year-old woman was referred for evaluation of an opacity in the right lower lung lobe. Despite lacking respiratory symptoms, she reported a long history of disordered eating involving the consumption of large amounts of salad oil followed by induced vomiting. High-resolution computed tomography showed ground-glass opacities with fat-tissue density, consistent with exogenous lipoid pneumonia caused by oil aspiration. Bronchoscopy revealed yellow secretions in the bronchial lumen, and cytologic examination confirmed lipid-laden macrophages. Histopathological analysis showed macrophages phagocytosing lipid droplets. The patient underwent cognitive behavioral therapy for her eating disorder, and six months after remission, radiologic findings had resolved.
