Question: Back Pain - need help understanding the MRI


 Diamama3 - Fri Oct 14, 2005 1:03 pm

I had a MRI and need help with the following results;

Axial scans thriugh the L3-L4 disc level are normal. A tiny central annular tear is present however.

Axial scans through the L4-L5 level show a central disc herniation minimally indenting the thecal sac and extending behind the superior endplate of the L5 vertebral body.

Axial scans thrught the L5-S1 level show diffuse disc bulge to the left side without significant nerve root compression. There is mild degenerative facet joint disease present.

There is a small synoval cyst seen posterolateral to the right L3-L4 facet joint.

Small cental disc herniation L4-L5.

L5-S1 bulging disc to the left side minimally indenting the thecal sac.


Please explain what the above mean

Thank You.

User avatar My first recommendation is switch doctors if yours currently is unwilling to explain an MRI finding! Now let's look at your MRI:

Axial scans through the L3-L4 disc level are normal. A tiny central annular tear is present however. The annular fibers that surround the disc are torn, but minimally at the L3/L4 disc
Axial scans through the L4-L5 level show a central disc herniation minimally indenting the thecal sac and extending behind the superior endplate of the L5 vertebral body.
When the disc tears significantly enough, the nucleus pulposis inside can squeeze out into the spinal column. This is a significant disc injury and most likely very painful. Axial scans through the L5-S1 level show diffuse disc bulge to the left side without significant nerve root compression. There is mild degenerative facet joint disease present. This disc has a mild injury to the fibers causing a "bulge" like what a balloon does when you squeeze it.
There is a small synovial cyst seen posterolateral to the right L3-L4 facet joint.
This is a lump that forms in the ligaments around right L3/L4 joint. Probably insignificant.
