What is cavernous sinus thrombosis?

ANSWER

Cavernous sinus thrombosis is a very rare, life-threatening condition that can affect adults and children. A blood clot blocks a vein that runs through a hollow space underneath the brain and behind the eye sockets. These veins carry blood from the face and head back to the heart.

The cause of cavernous sinus thrombosis is usually an infection. But other factors may play a role.

Cavernous sinus thrombosis is serious. It causes death in up to 30% of cases.
