Air in the cavernous sinus may be due to venous cannulation

Abstract

The discovery of air in the cavernous sinus may cause some alarm. It may well, however, simply be a consequence of retrograde air embolism from venous cannulation. It rarely has any adverse effects and is self-limiting in nature. We provide an illustrative case report.

Key words:

• Cavernous sinus
• air
• embolism
• venous
