Summary
Gas in the cavernous sinus is rare. This study found cavernous sinus gas in patients with sphenoid sinus fractures or after IV fluid infusion, with no associated symptoms.
Area of Science:
- Radiology
- Neurosurgery
- Otolaryngology
Background:
- Gas within the cavernous sinus is an uncommon radiological finding.
- The cavernous sinus is a critical venous plexus at the base of the skull.
Observation:
- This study reviewed three patients with gas in the cavernous sinus identified via computerized tomography (CT).
- Two patients had gas secondary to sphenoid sinus fractures.
- One patient developed cavernous sinus gas following intravenous fluid infusion.
Findings:
- No patients exhibited symptoms directly attributable to the presence of gas in the cavernous sinus.
- Despite the absence of cavernous sinus-specific symptoms, one patient had a poor prognosis due to associated trauma.
Implications:
- Identification of gas in the cavernous sinus on CT requires careful clinical correlation.
- Understanding the source and clinical significance of cavernous sinus gas is essential for patient management.
