Long-term exposure to liquid paraffin to combat constipation can lead to exogenous lipoid pneumonia, especially in the chronically aspirated elderly. The condition is often overlooked in medical history. Other exposure contexts include the nasal or pharyngeal application of mineral oil and the compulsive use of lipsticks. The non-degradable mineral oil accumulates in the alveoli, where it causes a pulmonary reaction with fibrosis.

Exogenous lipoid pneumonia has a predilection for lung bases, or it may be a diffuse shading that, on HRCT, assumes a ground glass or crazy pavement appearance. Opacities exhibit low attenuation numbers and may exhibit the “spontaneous angiogram” sign. The surface of BAL appears oily to the naked eye and, microscopically, contains increased numbers of lymphocytes and/or neutrophils in addition to the characteristic vacuolated lipid-laden macrophages.

The diagnosis of exogenous lipoid pneumonia is based on the history and examination of sputum or BAL, which shows lipid-loaded cells and floating oil that stains positively for oil red-O and Sudan black. Lung biopsy is not indicated for the diagnosis of this condition, except perhaps to diagnose paraphinoma, a solitary mass of exogenous lipoid pneumonia that can be mistaken for lung cancer. Not all patients with exogenous lipoid pneumonia will improve after stopping oil and corticosteroid therapy.
