This 50 y/o female patient with back pain was referred for MRI. Selected saggital and axial images shown above demonstrate a Type II split cord malformation. There is a single dural sac with a band splitting the tethered cord. There ia a syringohydromyelia above the level of the band. Note is also made of spinal dysraphic changes at L2-L3, the level of the band. Review of the articles by Pang et al.1,2,3 below will help to elucidate the rationale for a move away from the terms diastematomyelia and/or diplomyelia to describe split cord malformations.
