Diffuse alveolar haemorrhage associated with aerosol propellant use.

Diffuse alveolar haemorrhage (DAH) is a clinical syndrome resulting from injury to the alveolar microcirculation, most commonly associated with not only autoimmune disorders or connective tissue disease, but also a variety of infections, neoplasms and toxins. We report here a case of an otherwise healthy young man with DAH attributable to an inhalation injury resulting from use of aerosol spray paint.
