Diffuse endobronchial polyposis following a titanium tetrachloride inhalation injury

Area of Science:

• Pulmonology
• Toxicology
• Critical Care Medicine

Background:

• Inhalation injuries can lead to severe respiratory complications.
• Titanium tetrachloride exposure can cause significant airway damage.

Observation:

• A patient developed diffuse endobronchial polyps 5 weeks post-titanium tetrachloride inhalation injury, leading to persistent respiratory failure.
• The polyps contributed to obstructive airways disease and ventilator dependence.

Findings:

• Corticosteroid therapy significantly reduced the size and number of endobronchial polyps.
• The patient was successfully weaned from the ventilator following treatment.
• Complete polyp resolution and improved obstructive airways disease were observed up to 1 year post-injury.

Implications:

• Endobronchial polyps represent a potential delayed complication of inhalation injuries, including chemical exposures.
• This finding is relevant for understanding and managing prolonged respiratory failure in burn and inhalation injury patients.
• Corticosteroids may be an effective treatment for managing inhalation injury-induced endobronchial polyps.
