1. Sagittal SS-FSE T2-weighted image in a 23-gestational-week-old fetus demonstrates multiple bony anomalies in the cervicothoracic region and lumbar spine.
Sagittal SS-FSE T2-weighted image in a 23-gestational-week-old fetus demonstrates multiple bony anomalies in the cervicothoracic region and lumbar spine. There is an abnormally high termination of the spinal cord (arrow) with marked narrowing of the bony spinal canal at the upper and midlumbar spine (A).B, The lower lumbar bony spinal canal is more normal in caliber and contains abnormal neural tissue (arrow) in the sacral region. Findings are consistent with segmental spinal dysgenesis, and were confirmed by postnatal imaging.
