The fusion of cervical vertebrae is seen in Klippel-Feil syndrome. We found a fused bone in which the C7 and T1 vertebrae are fused. Incomplete or forming foramen transversarium [FT] is seen on the transverse process of T1. Costal facets are seen on the body and transverse process of T1 along with an incomplete or forming foramen transversarium. The incomplete foramen were seen bilaterally and of similar size. Knowledge of this rare variation will guide the radiologists for diagnosis and spine surgeons to decide the course of the surgery.
