Septic Bilateral Cavernous Sinus Thrombosis With Persistent Methicillin-Resistant Staphylococcus Aureus Bacteremia

Septic cavernous sinus thrombosis (CST) is an extremely rare diagnosis that is characterized by nonspecific signs and symptoms. It is often precipitated by a recent facial or sinus infection, as the venous supply from these areas drains into the cavernous sinus. This case highlights significant morbidity and mortality in septic CST where all aggressive treatments did not lead to clinical improvement, and the precipitating cause of the thrombosis was never found. The patient reported herein decompensated despite several investigations and treatment measures due to the lack of proper evidence-based approach.
