1 A, T2WI MR image demonstrates a dorsal indentation (arrow) and anterior displacement of the upper thoracic spinal cord. A, T2WI MR image demonstrates a dorsal indentation (arrow) and anterior displacement of the upper thoracic spinal cord. Increased cord signal and syringomyelia are present above the level of indentation. B, T2WI MR image status post laminectomy and resection of a posterior arachnoid web demonstrates resolution of the dorsal indentation, cord signal changes, and syringomyelia. M.A. Reardon et al.
