The anatomical variations of the internal jugular vein (IJV) is a well-documented phenomenon which may depend on the course of drainage, fenestration in the vein, bifid formation, variations in the tributaries and so on. However, a true duplication of the IJV is a rare entity on its own and is seldom reported in the literature. We report a case of true duplication of IJV which is an incidental discovery during the course of neck dissection.
颈内静脉（IJV）的解剖变异是一种有充分文献记载的现象，其可能取决于引流路径、静脉中的开窗、双叉形成、支流变异等。然而，IJV真正的重复是一种罕见的独立情况，在文献中很少有报道。我们报告一例IJV真正重复的病例，这是在颈部解剖过程中的偶然发现。
