Complete transection of spinal cord is an extremely rare occurrence, and usually associated with spinal instability, fracture or spondylolisthesis and also have associated systemic polytrauma involving multiple organs injury. However, a complete transaction of spinal cord unassociated with fracture or dislocation or without abnormality on X-ray and CT scan imaging is extremely uncommon. Kalfas et al. observed 11.2 % of cases had cord transection in the study of sixty-two cases spinal cord-injured patients, who underwent spinal MRI, were additionally had evidence vertebral injury. In 2010, Cha et al reported the first case of transection of cord in the cervical region in a 34- year- adult male, as the first case in literature, which was not associated with any vertebral body fracture or dislocation. Authors report an interesting case, 15-year boy, who had complete transection of the spinal cord associated with polytrauma following a motor vehicle accident, spinal X-ray and CT scan imaging was unremarkable, however spinal MRI scan established the diagnosis. Briefly, imaging, management and pertinent literature are reviewed.
