There is a comminuted fracture and marrow oedema in the anterosuperior corner and superior endplate of L1 vertebral body. The fractured anterosuperior corner of L1 vertebral body is attached to the anterior longitudinal ligament; however, the posterosuperior corner of L1 vertebral body is retropulsion. There is epidural haemorrhage along the posterior aspect of T12 and L1 vertebral bodies having maximum AP diameter of 8mm. The retropulsion L1 vertebral body along with epidural haemorrhage is causing severe compression over spinal cord. There is a focal defect in the substance of distal-most spinal cord at T12-L1 level with ill-defined abnormal hyperintensity is noted in the substance of cord at T11-12 level and in conus medullaris at L1 level.
These described imaging appearances are most suggestive of spinal cord transection with intramedullary haemorrhage. Small pre and bilateral paravertebral haemorrhage is also present at same level. The right-sided paravertebral haemorrhage is extending into right posterior pararenal space and having maximum TR diameter of 10mm. A focal breach is suggested in interspinous ligament at T12-L1 level.
Oedema is noted in soft tissues of the back. Overall these described imaging appearances are sequelae of antecedent trauma.
