Bilateral Multilevel Cervical Rib and Bilateral Omovertebra in Klippel-Feil Syndrome.

Background: Klippel-Feil syndrome was first described in 1912; a short neck, low posterior hairline, and decreased cervical joint range of motion are the classical triad of this disease. In this syndrome, which is rarely observed, the characteristics that have been reported include the following: scoliosis; Sprengel deformity; cervical rib; ear, nose, oral, and laryngeal abnormalities; structural abnormalities of the urinary system; and congenital heart diseases. However, bilateral omovertebra and bilateral multilevel cervical ribs have not been reported.
