Fig. 13B. —Right vertebral vein resembles paratracheal node in 62-year-old man with lung cancer in left upper lobe. Early (A) and delayed (B) phase scans of transverse contrast-enhanced CT show nonenhancing small nodule (arrow, A) at right aspect of trachea, which is similar to paratracheal node. On delayed phase scan, nodule (arrow, B) adjacent to trachea is enhanced same as vessels. Although vertebral vein usually ends at upper portion of brachiocephalic vein, right vertebral vein ends at lower portion of right brachiocephalic vein in this particular patient, which is why right vertebral vein resembles right paratracheal node.
