The wasp-waist sign is a radiographic appearance seen in patients with congenital block vertebra such as Klippel Feil syndrome. It results from the fusion of the vertebral bodies such that the anteroposterior diameter at the level of the affected discovertebral joint is smaller than the diameter at the superior and inferior limits of the vertebrae adjacent to uninvolved discs.
