    ### Response:
    How is Klippel Feil syndrome diagnosed? Klippel Feil syndrome (KFS) is typically diagnosed when X-rays or other imaging techniques show fusion of cervical vertebrae. X-rays of the entire spine should be performed to detect other spinal abnormalities, and additional imaging studies may be needed to assess the extent of the abnormality.
