Decompression sickness often manifests as central nervous system impairment. We report a 49-year-old woman who developed an unusual case of spinal cord decompression sickness presenting as complete Brown-Sequard syndrome. Initial MRI revealed increased signal intensity in the left side of the cervical cord at the level of C2-C3. A second MRI at 10 days post-injury showed signal abnormalities corresponding to an infarction in the posterior spinal artery territory. After two weeks of intensive treatment with various HBOT regimens, the clinical outcome was still poor, but at six months after the injury her neurological condition was greatly improved, with only slight impairment of proprioception on the left when walking remaining.
