Lower extremity weakness. Cervical spine:Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is mild loss of cervical lordosis with minimal anterolisthesis of C3 on C4 and C4 on C5 and minimal retrolisthesis of C5 on C6. The cervical spinal cord has normal signal characteristics and overall morphology. Bone marrow signal is benign with no suspicious osseous lesions.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise to the spinal canal or right neural foramen. Mild to moderate left neural foraminal stenosis related to uncovertebral hypertrophy and facet arthropathy.C4-5: No significant compromise to the spinal canal or right neural foramen. Mild left neural foraminal narrowing.C5-6: No significant compromise to the spinal canal. Moderate bilateral neural foraminal stenosis, left worse than right, related to uncovertebral hypertrophy and facet arthropathy.C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.Thoracic Spine:There is abnormal T2 signal involving the ventral aspect of the cord bilaterally from the upper T7 upper T9 levels. No additional cord lesions or cord mass is appreciated.Thoracic vertebral body heights are maintained. Alignment is maintained. Mild degenerative changes are seen including small Schmorl's nodes, disc height loss, as well as small disc bulge at the T6-T7 level. There is no significant spinal canal or neural foraminal stenosis. Bone marrow signal is benign with no suspicious lesions. Scattered foci of T1 hyperintensity are compatible with small hemangiomas or foci of fat. Paraspinous soft tissues are grossly unremarkable.
1. Abnormal T2 hyperintensity involving the ventral thoracic cord bilaterally from the upper T7 to the upper T9 levels. Findings are suspicious for infarct in the anterior spinal artery territory, although inflammatory myelitis remains a possibility. Diffusion sequence may be attempted of the thoracic cord for further evaluation if clinically indicated.2. No significant cervical spinal canal stenosis or cervical cord signal abnormality. Mild degenerative changes as detailed above.
