MRI findings in cervical spinal cord type II neurological decompression sickness: a case report

Decompression illness affecting the cervical spinal cord is uncommon. We report a case that presented with mixed signs and symptoms of cervical myelopathy and Type II neurological decompression sickness. This presented a diagnostic dilemma that required the use of magnetic resonance imaging (MRI) scan to elucidate the underlying cause. Cervical spine MRI revealed the presence of tiny hypointensities and edema within the spinal cord that corresponded to the clinical findings. The patient recovered with residual neurological deficits after hy-perbaric oxygen (HBO2) therapy. To our knowledge, these MRI findings have yet to been described in literature and we recommend the use of MRI to assist diving physicians in the management of complex cases as long as it does not delay recompression.
