External jugular vein (EJV) is a significant vein draining the head and neck is being used for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of EJV provide clues towards underlying cardiac pathology, clear knowledge about the variations of EJV and associated superficial veins is important for the surgeons to prevent complications during procedures. During routine cadaveric dissection we observed a rare case of complete absence of EJV and Cephalic vein (CV), the Posterior division of Retromandibular vein (PRMV) and the Posterior auricular vein (PAV) entered into Sternocleidomastoid muscle (SCM), the Superior thyroid vein (STV) drained into the Common facial vein (CFV) all these variations were observed only in the left side and no such variations were seen in right side. Details about these variations and the related angiogenesis were discussed.
