[Post-traumatic L5-S1 root avulsion. Myelographic and x-ray computed tomographic study. Apropos of a case. Review of the literature].

A patient presented an avulsion of left L5-S1 roots, with S1 meningocele, following a road accident. Saccoradiculography and CT scan imaging, even without contrast, allowed identification of total lesion in a suggestive clinical context. The characters of the CT scan images are emphasized. Images showed also the presence of pseudo-meningoceles and absence of roots.
