Vertebral Malformation
This disease is characterized by vertebral malformations. Examples include block vertebrae, hemi-vertebrae, or butterfly vertebrae. Neurologic signs occur as a result of spinal cord compression secondary to abnormal vertebral morphology. Compression primarily occurs along the dorsal and lateral aspects of the spinal cord, but can occur anywhere.
