Cavernous sinus thrombosis
Toggle: English / Spanish
Cavernous sinus thrombosis is a blood clot in an area at the base of the brain that contains a vein, which carries blood from the brain to the heart. This area is called the cavernous sinus.
Cavernous sinus thrombosis is usually caused by a bacterial infection that has spread from the sinuses, teeth, ears, eyes, nose, or skin of the face.
You are more likely to get this condition if you have an increased risk of blood clots.
