CT of the thoracolumbar spine –
There are 7 lumbar vertebrae. The 13th thoracic vertebra is an asymmetric thoracolumbar vertebra.
Extrusion of mineralized disc material into the ventral epidural space is noted et T12/13. The vertebral canal diameter is reduced by 60 %. More material is located within the right ventral epidural space, the dural tube is compressed and displaced dorsally and to the left. The dorsal and ventral contrast column are diminished from T11 to T13 indicating spinal cord swelling. Multifocal chondroid disc degeneration is noted.
Surgical decompression is recommended. A rightsided approach would be preferred.
Please note the asymmetric thoracolumbar transitional vertebra.
