Spontaneous cerebral air embolism associated with remote lung surgery.
BACKGROUND
Airembolism without obvious trauma or surgery is rare.


METHODS
Case report.


RESULTS
Four years after resection of a non-small cell lung cancer, a 57-year-old man presented with recurrent episodes of sudden onset neurological deficits. Head computer tomographic (CT) scans suggested air embolism, and further investigations showed a potential anastomosis between a pulmonary air cavity and a pulmonary vein. He was treated surgically by debridement of the bronchovascular bundles surrounding the air cavity. The patient had no further neurologic deficits during 10 months of post-surgical follow-up.


CONCLUSIONS
In the absence of trauma, sinus disease, recent surgery, or vascular procedures, the presence of air in the brain is unusual, and pulmonary sources of air embolism should be considered.
