MR findings in scuba diving-related severe spinal cord decompression sickness

A 32-year-old man made a dive to 35 m seawater for 40 min.
On surfacing without decompression stops, he became unconscious and remained quadriplegic. He manifested a C4 sensory level.
MR of the cervical spine was performed 5 days after the injury.
A) Sagittal and B) axial FSE T2-weighted MR images showed areas of increased signal intensity in the dorsal columns of the spinal cord at C2-C4 levels.
