Exogenous lipoid pneumonia

Exogenous lipoid pneumonia is a form of lipoid pneumonia. Please refer to the main article for a broad discussion. 

In terms of the onset of the presentation, it can be divided into two different forms:

  • acute exogenous lipoid pneumonia
    • uncommon and typically is caused by an episode of aspiration of a large quantity of a petroleum-based product
      • typically occurs in children due to accidental poisoning
      • can also occur in performers who use liquid hydrocarbons for flame blowing (i.e. fire-eaters): hence also called fire-eater's pneumonia or fire-eater's lung 4
  • chronic exogenous lipoid pneumonia
    • usually results from repeated episodes of aspiration or inhalation of animal fat or mineral or vegetable oils over an extended period
    • typically occurs in older patients but also has been reported in children as well as in infants when mineral oil is used as a lubricant to facilitate feeding
    • also can occur in patients without a predisposing anatomic or functional abnormality in swallowing
    • aspiration of fats or oils has been reported in patients with a history of chronic use of mineral oil or petroleum-based lubricants and decongestants
