There are many clinical indications for neonatal spinal imaging. The advantages of real-time imaging and improved spatial resolution have broadened the field of ultrasound's applicability to include the neonatal spinal cord. The authors present a case study of a tethered cord in which sonography was the initial imaging exam of choice, and magnetic resonance imaging confirmed the diagnosis. The authors also review the sonographic characteristics and discuss the pathogenesis of a tethered spinal cord.
