Abstract

Acute exogenous lipoid pneumonitis is a kind of chemical pneumonitis following the aspiration of volatile hydrocarbon compounds. The clinical and radiological findings are nonspecific. However, it can be diagnosed by the presence of lipid-laden macrophages in bronchoalveolar lavage fluid on the basis of a history of petroleum-based product aspiration. Herein, we report acute exogenous lipoid pneumonitis after unintentional aspiration of diesel fuel during siphon-age in a 31-year-old male. Initially the patient had cough, chest pain, and blood-tinged sputum. The purpose of this case report is to review the radiologic manifestations and the previous literatures.

A smear shows many neutrophils and foamy macrophages (oil red O stain, × 400) (D). The cytoplasm is full of red-staining cytoplasmic vacuoles filled with lipid that displaced nucleus to the periphery (oil red O stain, × 400) (E). F. Ten days after the admission, follow-up chest radiograph shows improvement of ill-defined increased opacity in both lower lungs with residual lesions.
