Posttraumatic subacute ascending myelopathy in a 24-year-old male patient.

Posttraumatic subacute ascending myelopathy is a rare late complication of spinal trauma. We present a case of 24-year-old male patient of motor vehicle accident who initially presented with T12 vertebral fracture and associated cord compression and signal changes in lower dorsal cord causing paraplegia with bladder and bowel involvement. In the subsequent week, he developed complete paraplegia with cord signal abnormality on magnetic resonance imaging extending cephalad from the injury site to involve the cervicomedullary junction. The patient clinically and radiologically improved over 6 weeks on steroid treatment.
