Scintigraphic findings in Klippel-Feil syndrome

The clinical triad, described by Klippel and Feil in 1912, consists of a short neck, low dorsal hair line, and restricted neck mobility. It is the result of congenital synostosis of several cervical vertebrae. In 50% of these patients, the full clinical triad is not even present. However, there are a wide variety of associated congenital abnormalities: urogenital, neurological, cardiovascular, respiratory, and musculo-skeletal have been described. In the majority of cases, diagnosis of the Klippel-Feil syndrome is established in conjunction with the clinical symptoms and radiographic appearance. On occasion, certain characteristics of the syndrome may be identified on a bone scan as the current case shows.
