Type II decompression sickness (DCS) usually manifests as myelopathy;
however, there are no reports of Brown-Sequard syndrome in association

II DCS presenting as partial Brown-Sequard syndrome. MRI of the thora
cic spine revealed two punctate foci of increased signal intensity in
the right T6 spinal cord.
