Sonography of jugular vein thrombosis.

The sonographic findings in three patients with jugular vein thrombosis are described. In each case, intraluminal clot appeared as a solid mass composed of midamplitude echoes. In one patient, near complete resolution of the thrombus was documented by serial sonograms over a 3 month period. High-resolution sonography of the neck is a reliable method to establish the diagnosis of jugular vein thrombosis.
