Dural sinus thrombosis is clotting in the veins that drain blood from the brain.
Symptoms may include severe headache, vomiting, blurred vision, seizures, confusion, weakness, or symptoms that look like a stroke.
Imaging helps confirm whether a clot is blocking the brain’s venous drainage and shows how extensive it is or whether there are complications such as swelling or bleeding.
CT venography or MR venography is often used to confirm the clot and assess how much of the venous system is involved.
Treatment usually includes anticoagulation and management of the underlying trigger or complication.
