Cavernous sinus thrombosis (CST) is the formation of a blood clot within the cavernous sinus, a cavity at the base of the brain which drains blood from the brain back to the heart.[1] Symptoms may include headache, eye pain, bulging eyes, fever, and double vision.[1] Often one eye is involved initially followed by involvement of the second eye.[3] Complications may include meningitis, brain abscess, and pituitary insufficiency.[2]
There are two types–septic (infection) and aseptic (not infection).[3] Risk factors include infections of the face such as boils on the nose, sinusitis, and dental infections.[2] The bacteria most commonly involved include Staphylococcus aureus and Streptococcus.[2] Other risk factors include injury, surgery, and easy blood clot formation.[3] Diagnosis is generally based on either CT scan or MRI.[2] It is a type of cerebral venous sinus thrombosis.[3]
It is a medical emergency.[1] Treatment may include antibiotics, heparin, and corticosteroids.[1] Occasionally surgery is required to drain an abscess the contributed to the condition.[1][3] Up to 30% of people die, despite treatment.[1] Among those who survive vision loss and seizures may occur.[1] Cavernous sinus thrombosis is rare, affecting possibly 0.2 to 1.6 people per 100,000 per year.[1][3]
