  		Figure 1. (a) A CT image reveals ring-shaped enhancement and central low density in the left retromandibular vein (arrow), suggesting venous thrombosis. On more caudal level, vascular enhancement is not observed due to the thrombus both in (b) the left external jugular vein (arrow) and (c) the left internal jugular vein (arrow).

  		Figure 2. Intense uptake of 18F-fluoro-2-deoxy-D-glucose (FDG) corresponding to lesions suspected of thrombus formation in the left internal and external jugular veins. Continuous accumulation ranged from the area adjacent to the left parotid gland to the insides of two veins (arrows).

  		Figure 3. Histological features (haematoxylin and eosin staining) of the left external jugular vein. (a) A whole section of the vein, (b) peripheral portion and (c) central portion are demonstrated. The lamellar structure of venous wall was destroyed and collagenous fibres intruded inside from the wall. No cancer cells were detected in the organized thrombus. Infiltration by foam cells and lymphocytes can clearly be observed in the margin, whereas plasma cells and neutrophils are predominantly recognized in the central area.
