It is characterized by the presence of a complete or incomplete sagittal cleft of varying extent that splits the spinal cord into two hemicords at the conus medullaris, or filum terminale. It is often associated with splaying of the posterior vertebral elements. This condition is caused by an osseous, cartilaginous, or fibrous septum. It may be isolated or associated with other segmental anomalies of the vertebral bodies. When the split does not reunite distally to the spur, the condition is referred to as a diplomyelia or true duplication of the spinal cord. The clinical features may include neurologic deficits of the lower limbs and perineum, causing gait disorders, sphincter disturbances, muscular atrophy, reflex changes, congenital scoliosis, and foot deformities.
