[Paravertebral ganglioneuroma in an adult. Discovery during a spinal attack revealing multiple sclerosis]

A paravertebral ganglioneuroma was discovered in a 25 year-old woman presenting a transverse spinal syndrome at the same level. Exeresis necessitated sacrifice of the ninth left intercostal artery, but paraplegia regressed completely under corticotherapy. Additional exploration and subsequent clinical evolution revealed multiple sclerosis, of which the pavaplegia had been a manifestation. The authors discuss ganglioneuroma in the adult, a rare tumour, and the possibility of a link with multiple sclerosis. The association seems fortuitous despite the fact that the tumour and the transverse myelitis occurred at the same level.
