 MRI thoracic spine: There is no evidence of abnormal enhancement in the spinal cord. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable.MRI lumbar spine: The spinal cord displays normal signal signal and morphology, without abnormal enhancement. However, there are partially imaged fusiform enhancing lesions involving multiple sacral nerve roots, the largest of which measures 15 mm in diameter in the left S2-3 neural foramen. There is mild anterolisthesis of L4 on L5, where a disc bulge in conjunction with posterior element hypertrophy results in marked spinal canal stenosis and bilateral neural foraminal stenosis. There is also a central disc extrusion at L1-2 and a small disc bulge at L5-S1, which results in mild spinal canal and mild right and moderate left neural foraminal stenosis. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable.
1. No evidence of enhancing lesions in the thoracic and lumbar spinal cord.2. Multiple partially imaged fusiform enhancing lesions involving multiple sacral nerve roots may represent inflammatory demyelinating polyneuropathy or peripheral nerve sheath tumors.3. Multilevel degenerative spondylosis of the lumbar spine, which is most pronounced at L4-5.
