Cavernous sinus gas

Cavernous sinus gas locules can be seen in several settings.

  • iatrogenic pneumocephalus secondary to gas embolism (especially venous gas embolism) from IV access (can be a relatively common finding in the absence of direct trauma and does not require treatment)
  • traumatic pneumocephalus: in the context of trauma, sphenoid or skull base fracture needs to be excluded in this context
  • very rarely infection from a gas-forming organism
