Jugular vein thrombosis is a clot in one of the major veins in the neck and can be related to infection, catheters, cancer, or clotting disorders.
Symptoms may include neck pain, swelling, tenderness, fever, or visible fullness in the neck, though some cases are found during imaging for another reason.
Imaging helps confirm the clot, show how far it extends, and look for complications such as infection or spread into nearby veins.
Ultrasound and CT can help confirm the clot and look for related swelling or extension.
Treatment may include blood thinners, infection treatment when relevant, and management of the underlying cause.
