Cavernous sinus thrombosis - Overview

Definition of Cavernous sinus thrombosis:

Cavernous sinus thrombosis is a blood clot in the cavernous sinus. The cavernous sinus is a cavity at the base of the brain that contains a vein, several nerves, and other structures. The vein carries deoxygenated blood from the brain and face back to the heart.

The vein and cavity run between the large bone at the base of the skull (sphenoid bone) and temporal bone (near the temple).

Causes, incidence, and risk factors:

The cause of cavernous sinus thrombosis is usually a bacterial infection that has spread from the sinuses, ears, eyes, nose, or skin of the face.
