Diastematomyelia is a form of spinal dysraphism involving sagittal clefting of the spinal cord, conus medullaris, and/or filum terminale into two hemicords. It can be an isolated finding or can be associated with meningomyelocele or meningocele. In this report, we present postoperative spinal ultrasonography findings in a patient with diastematomyelia and a tethered cord. © Turkish Society of Radiology 2005.
