Due to inadvertent inhalation of mineral oil.
Plain film
• Chronic lower lobe consolidation, may be focal/mass-like or multi-focal
CT
• Fat density attenuation/consolidation
Mostly due to alveolar rupture from increased intra-alveolar pressure (e.g. asthma, aspiration of foreign body, mechanical ventilation or trauma). Other causes include disease affecting the alveolar wall directly (e.g. pneumonia, ARDS or COPD), tracheal perforation and oesophageal rupture.
PLAIN FILM
• Look for air giving the heart/mediastinum a more crisp outline than normal.
• Gas in the soft tissues of the neck.
• Large volumes dissect inferiorly into the retroperitoneum/peritoneum.
