Cervical spine abnormalities and instability with myelopathy in warfarin-related chondrodysplasia : 17-year follow-up

A patient with warfarin embryopathy developed progressive cervical spinal myelopathy owing to bony cervical spinal damage. While there are several descriptions of warfarin embryopathy, the long-term complication of cervical spinal instability has not been reported. This cervical instability may, as in our patient, cause severe neurological dysfunction or even sudden death; therefore, it is important that pediatric radiologists should be alert to this condition.
