Duplication of internal jugular vein - An incidental finding

Duplication of the internal jugular vein is a rare anatomic variation that may occasionally be encountered during neck surgeries. This anomaly presents as two separate internal jugular veins instead of the typical single vein. Understanding and recognizing this variability is critical for surgeons to avoid unwanted injury and ensure a successful surgical outcome. The objective of this case report to understand the variation in anatomy of internal jugular vein, explain the presentation of internal jugular vein duplication, emphasizes the importance of careful dissection techniques when anatomical abnormalities are encountered during neck surgery and to discuss literature and hypothesis pertaining to its embryology of internal jugular vein duplication.
