Brown-Séquard syndrome, while uncommon, is a neurological condition that classically results from the hemisection of the spinal cord as a result of a penetrating injury to the spinal cord. We present a reported case of blunt trauma causing a high-energy cervical burst fracture/dislocation with a significant cord signal change producing Brown-Séquard syndrome. In this case, the burst fracture at the level of C5 obtained from the motor vehicle accident led to the damage of the left-sided lateral spinal thalamic tract, descending lateral cortical spinal tracts, and ascending dorsal column. This is a unique case of blunt nonpenetrating trauma leading to a high-energy cervical burst fracture/dislocation causing significant cord signal change on T2-weighted magnetic resonance imaging (MRI). These physical changes produced symptoms of neurologic impairment commonly seen in those patients with Brown-Séquard syndrome.
