Internal and external jugular vein thrombosis with marked accumulation of FDG

Abstract

We report an unusual case of idiopathic internal and external jugular vein thrombosis. Positron emission tomography (PET) using (18)F-fluoro-2-deoxy-D-glucose (FDG), which was conducted to assess subclinical malignancy, revealed intense uptake of FDG, corresponding to thrombus within the left internal and external jugular veins. Although FDG-PET is widely used in differentiating between malignant and benign diseases, we should bear in mind that this benign entity can demonstrate high accumulation of FDG.
