Cavernous sinus thrombosis Cavernous sinus thrombosis
1 answer
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 factorsThe cause of cavernous sinus thrombosis is usually a bacterial infection that has spread from the sinuses, teeth, ears, eyes, nose, or skin of the face. Persons with conditions that cause an increased risk of blood clots may also develop cavernous sinus thrombosis.
Symptoms- Bulging eyeballs
- Cannot move the eye in a particular direction
- Drooping eyelids
- Headaches
- Vision loss
Tests that may be ordered include:
- CT scan of the head
- Magnetic resonance imaging (MRI) of the brain
- Sinus x-ray
Cavernous sinus thrombosis is treated with high-dose intravenous (through a vein) antibiotics. Sometimes surgery is needed to drain the infection.
Expectations (prognosis)Cavernous sinus thrombosis can be fatal. However, the death rate of this condition has improved tremendously since the introduction of antibiotics.
Calling your health care providerCall your doctor right away if you have:
- Bulging of your eyes
- Drooping eyelids
- Eye pain
- Inability to move your eye in any particular direction
- Vision loss

The dangerous triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. Due to the special nature of the blood supply to the human nose and surrounding area, it is possible (although very rare) for retrograde infections from the nasal area to spread to the brain.
This is possible because of venous communication (via the ophthalmic veins) between the facial vein and the cavernous sinus. The cavernous sinus lies within the cranial cavity, between layers of the meninges and is a major conduit of venous drainage from the brain.
It is a common misconception that the veins of the head do not contain one way valves like other veins of the circulatory system. In fact, it is not the absence of venous valves but the existence of communications between the facial vein and cavernous sinus and the direction of blood flow that is important in the spread of infection from the face

A cavernous malformation in the left parietal lobe is a cluster of abnormal, dilated blood vessels that can result in neurological symptoms such as seizures, headaches, or neurological deficits. Treatment options may include observation, medications to manage symptoms, or surgical removal depending on the severity of symptoms and location within the brain. Regular monitoring may be necessary to evaluate for changes in symptoms or potential risks.
