Acute exogenous lipoid pneumonia
Citation, DOI, disclosures and article data
Acute exogenous lipoid pneumonia is an uncommon form of exogenous lipoid pneumonia and is typically caused by the aerosolization and aspiration of a highly viscous hydrocarbon, such as vegetable oil, mineral oil or petroleum jelly 5. The more common pulmonary toxicity exerted by hydrocarbons is an aspiration pneumonitis, typically those of low viscosity and high volatility, and may be a sequela of either aspiration or ingestion.
Non-specific but may show areas of consolidation and with a lower lobe involvement in a majority of patients 2.

Other described changes include
