C6-7 fracture. Weakness to right tricep and sensory loss to 2nd digit right hand. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. Alignment is maintained. There is edema involving the C6 and C7 vertebral bodies and C6-7 disc space which may be related to trama given history or degenerative disease. Right C6 lamina fracture extending into the right C6-7 facet joint better assessed by CT. Ligaments are intact. Diffuse congenital narrowing of the cervical spinal canal is noted.There is abnormal T2 hyperintensity in the cervical cord at C6-7 involving the central cord bilaterally.The cervical spinal cord has otherwise normal signal characteristics and overall morphology.Mild 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: Minimal disc bulge and right uncovertebral hypertrophy result in mild right neural foraminal narrowing. No significant compromise to the spinal canal or left neural foramen.C4-5: Minimal disc bulge. No significant compromise to the spinal canal or neural foramina.C5-6: No significant compromise to the spinal canal or neural foramina.C6-7: There is loss of disc height and small disc osteophyte complex. Minimal narrowing of the spinal canal. Mild bilateral neural foraminal narrowing, right worse than left related to uncovertebral hypertophy.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.
1. Congenital narrowing of the spinal canal with mild superimposed degenerative changes, relatively worse at C6-7, as detailed above. There is mild right C3-4 and mild bilateral C6-7 neural foraminal stenosis. No high grade spinal canal or neural foraminal stenosis. 2. Abnormal T2 hyperintensity involving the central cord at C6-7 bilaterally which may represent sequela of prior trauma given history. Please note right C6-7 fractures are better seen on prior CT. No findings to suggest nerve root avulsion. Edema involving the C6 and C7 vertebral bodies and intervening disc space compatible with prior trauma.
