Answer

Most cases of septic cavernous sinus thrombosis (CST) are due to an acute infection in an otherwise healthy individual. However, patients with chronic sinusitis or diabetes mellitus may be at a slightly higher risk.

The causative agent is generally Staphylococcus aureus, although streptococci, pneumococci, and fungi may be implicated in rare cases.
