Postirradiation spinal root cavernoma.

摘要

The consequences of radiotherapy on the spinal cord have been well known for several years 1. They include acute my-elopathy corresponding to spinal cord infarction, mild sensory myelopathy occurring several months after irradiation, chronic progressive myelopathy and lower motor neuron syndrome. The pathogene-sis of the latter is not clearly established. It could be related to loss of motor neuron cell bodies or damage to cauda equina roots 1. We report an observation of spinal root cavernoma induced by radiotherapy.
