We are reporting here a unique cascade-like arrangement of single cusps in the right internal jugular vein observed ina formalin-fixed embalmed cadaver of a 65 year old male which has not been observed and described in the literature. The anomaly may be of interest not only to the morphologist but also to the clinical practitioner working on the internal jugular veins.
