Lateral skull and cranial cervical spinal radiographs of a 6 year old female Griffon Bruxellois presented with tetraparesis and following MRI diagnosed with symptomatic CM and SM. The skull has rostro-cranial doming and a “copper beaten” appearance due to convolutional markings relating to the gyri and presumed raised intracranial pressure. The supraoccipital bone is flattened (blue arrow) and the occipital crest is small (red arrow). A large cervical syrinx has resulting in widening of the cervical spinal canal with thinning and scalloping of the vertebrae (yellow arrow). A MRI confirmed CM, SM, and ventriculomegaly. The maximum width of the syrinx in the cervical spinal cord in a transverse section at the level of C2 was 8 mm.
