Lipoid pneumonia is suggested when there is a history of chronic oral or intranasal use of an oil- or lipid-based product. The characteristic findings of lipid materials in CT or MRI are used in the diagnosis of lipoid pneumonia. The presence of lipid-laden macrophages in the sputum, bronchoalveolar larvage or pulmonary parenchymal biopsy confirms the diagnosis. Sputum study is simple and inexpensive.

We report a case of lipoid pneumonia of 75 year old male with cough and sputum, confirmed by sputum study, and review the literature.
