Abstract

Accessory cleido‑occipitalis muscle is an additional muscle fascicle derived from occipital portion of trapezius muscle inserted into the clavicle. Since its location is confined to neck region, it is also known as cleido‑occipitalis cervicis. In the present case, we report a unique case of accessory cleido‑occipitalis muscle derived from trapezius muscle. It was more tendinous than muscular and its tendon was extending medially, crossing the supraclavicular triangle of the neck horizontally in close approximation of clavicle. A narrow gap between them was a passage for the external jugular vein with its possible entrapment. The external jugular vein is a clinically important superficial venous channel required for many therapeutic interventions. The possible entrapment of it could hinder these approaches and also could lead to several complications
