[Lumbar radiation myelopathy. Case report on localization of lumbar radiation sequelae]

The case of a patient with a radiation lesion of the lumbosacral cord following prophylactic radiation therapy of the paraortic lymph nodes for seminoma is reported. Seven months after radiotherapy he suffered from a pure anterior cell syndrome, followed by a loss of pain and temperature sensation. Ten years later he developed a complete transversal syndrome at the level of L 1. This case indicates the existence of a lumbar radiation myelopathy caused by a lesion at the level of the conus medullaris.
