Abstract
Spinal dysraphism refers to incomplete embryologic development of the dorsal midline. Frequently, it is not clinically obvious and lack of treatment can lead to progressive neurological damage. Early diagnosis of occult defects can allow appropriate surgical intervention and prevent neurological deficits. High-resolution real-time ultrasound was used to screen [human] infants with various cutaneous lumbosacral markers, all of whom were at risk of occult spinal dysraphism. Preliminary results suggest that ultrasound is a reliable screening procedure and could obviate the need for more costly and invasive tests.
