Objective. To describe the features of sonographic duplication artifacts that we have occasionally seen when imaging the spinal cord of infants and children, mostly with postrepair myelomeningocele. Methods. Sonography of the spine was performed for the evaluation of neonates with suspected spinal cord abnormalities and of older children in the follow-up of postrepair open-spine defects. Results. Each of our patients had a single spinal cord, but the duplication artifact was seen with 2 brands of scanners and with both linear array and vector array transducers. Conclusions. The finding of duplication artifacts when imaging the spinal cord of infants and children should be recognized as such and should not be misinterpreted as representing diastematomyelia or diplomyelia.
