The low signal seen in the central cord on both T1-weighted spin echo and relatively T2-weighted MPGR and GRE sequences has been ascribed by Kulkarni et al, to cord contusion with intramedullary hemorrhage, producing characteristic deoxyhemoglobin signal in the cord.This has a poor prognosis as opposed to cord signal which is high on T2-weighted images or of mixed signal.  The finding of severe spinal cord injury in this case is not surprising since flexion teardrop-type injuries carry a poor prognosis due to the severity of impaction of the bony fragments on the cord.
