"C4-5 disc: anterior and right posterolateral disc protrusion and osteophyte producing mild right intervertebal foraminal stenosis but no definite nerve root compression,"
C4-5 are the fourth, and fifth vertebra down from the top of your neck anterior is the front, the disk is protruding to the front and right, ostephytes are small bony growths, the vertebral foramina are small grooves or holes in the side towards the rear of the vertebra that the nerve roots coarse out of, stenosis means narrowing, so they have narrowed but the nerves are not being compressed.
"C5-6 disc: anterior disc protrusion and osteophyte. No significant posterior disc abnormality."
This is the next joint down its the same sort of thing refer to the C4-5 explanation
"C6-7 disc: Mild concentric disc bulge without discrete disc herniation or neural impingement"
Mild bulging all around the disk, no rupture of the disk, no nerve compression
"T1-2 disc: mild broad posterior disc protrusion without apparent neural impingement. IMPRESSION:mild multilevel degenerative disc disease as noted above with RIGHT FORAMINAL STENOSIS at C4-5 without apparent neural impingement. No intrathecal abnormality"
T1-2 is at the base of your neck, posterior is at the back, disc protrusion is not compressing the nerves. Multilevel DDD, DDD can be many things like disc narrowing, and a lack of moisture in the discs, small bony growths, and arthritis.
intrathecal means inside the tough membrane that surrounds the spinal cord there is no abnormality here.
"MRI LUMBAR SPINE:
Conus medullaris appears normal. There is mild anterior wedging of the T11-12 disc with mild broad based posterior disc protrusion but no discrete disc herniation or neual impingement."
Conus medullaris is the end of the spinal cord where it branches out into a bundle of individual nerves.
Anterior wedging is when the front of the vertebral body has narrowed, T11-12 is the seventh joint from the bottom of your spine. For the rest refer above its just a repeat of problems at other levels.
"T12-L1 disc: within normal limits"
Next joint down, its normal.
"L1-2 disc: mild anterior disc bulge w/o posterior disc contour abnormality"
Next joint down, front of disc is bulging, back of disc is ok.
"L2-3 disc: within normal limits, Mild bilateral facet arthropathy."
Disc is ok, but the small joints at the back of the vertebra that guide motion of the vertebra have arthritis.
"L3-4 disc: no disc contour abnormality. Mild bilateral facet arthropathy"
Same as previous level
"L4-5 disc: Far lateral disc protrusion on right w/o nerve root compression"
lateral means to the side, refer to previous explanation for the rest.
"L5-S1 disc: left posterolateral disc protrusion.W/O impingement nerve root. Mild bilateral facet arthropathy."
Refer above.
"No mass seen."
Thats good
This is not an MRI reading its just an explanation of some common medical terms.
All the best
