 Craniocervical junction appears within normal limits. Vertebral body heights are within normal limits. Alignment is grossly maintained. Bone marrow signal is benign. There is diffuse narrowing of the upper and mid cervical spinal canal on a congenital basis primarily related to pedicle hypoplasia. Neural foramina are diffusely narrowed on a congenital basis as well.There is focal increased signal within the cord at C5-C6 at the site of a disc extrusion which is suspected to represent edema. Individual levels as below:C2-C3: Mild to moderate right neural foraminal stenosis. No significant spinal canal or left neural foraminal stenosis. C3-C4: Moderate left greater than right neural foraminal narrowing. Mild to moderate spinal canal narrowing on a congenital basis.C4-C5: Mild to moderate left neural foraminal stenosis and mild right neural foraminal stenosis. There is mild to moderate spinal canal stenosis on a congenital basis. C5-C6: There is a disc extrusion causing moderate to severe narrowing of the spinal canal. There is moderate to severe left and moderate right neural foraminal stenosis. Abnormal T2 signal noted in the bilateral cervical cordC6-C7: Mild to moderate right and minimal left neural foraminal narrowing. No significant spinal canal narrowing.C7-T1: No significant spinal canal stenosis. Moderate left and mild right neural foraminal narrowing.Focus of low signal posterior to the thecal sac at T2-T3 seen only on the sagittal sequences is suspected to represent ligamentous calcification and causes mild narrowing of the spinal canal.
1.Disc extrusion at C5-C6 results in moderate to severe spinal canal narrowing and T2 hyperintensity involving the cervical cord which is suspected to represent edema. There is also moderate to severe neural foraminal narrowing on the left and moderate on the right.2.Congenital narrowing of the upper and mid cervical spinal canal as well as of the neural foramina. There are mild superimposed degenerative changes with resulting stenoses as detailed above. 3.Focus of low signal posterior to the thecal sac at T2-T3 may represent a focus of ligamentous calcification and causes mild narrowing of the thoracic canal.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
