Klippel-Feil syndrome is a congenital fusion of cervical vertebrae that is clinically characterized by the classic triad of short neck(brevicollis), low posterior hair line, and severe restriction of neck motion. Because Klippel-Feil syndrome occurs in a heterogeneous group of patients unified only by the presence of a congenital defect in the formation or segmentation of the cervical spine, numerous associated abnormalities of spine & other organ systems may be present. The authors present a 48-year-old patient with multiple congenital cervical fusions who developed motor weakness after car accident. The combined cervical lesions of this patient included atlanto-occipital assimilation, scoliosis, hemiver- tebra, posterior spina bifida, cervical spondylosis, and hypermobility of the upper cervical segment. Clinical presen- tation varied considerably because of all the associated syndromes and anomalies that can occur in patient with Klippel-Feil syndrome. To reveal some associated anomalies associated with Klippel-Feil syndrome must be needed a careful complete history, physical examination, and image studies.
