Name of the Patient : Abc Xyznnisha Malmn / F / 53 yrs.
Referred by : Dr. Abc Xyzrankar.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache wtih radiation of pain to BLE.
EXAMINATION :
M.R.I of the lumbo-sacral spine was performed using the following parameters :
5 mm thick T1 Weighted and T2 Weighted sagittal images.
5 mm thick T1 Weighted and T2 Weighted axial images.
OBSERVATION :
There is mild forward translation of the L5 vertebra over the S1 vertebra. The lumbar intervertebral discs show loss of water content.
A left paracentral disc herniation is seen to indent the thecal sac and the traversing left S1 nerve root at the L5-S1 level. The traversing left S1 nerve root appears to be inflamed.
A posterior disc herniation is seen to indent the thecal sac and narrow both neural foramina at the L4-L5 level. A right far lateral (extraforaminal) disc herniation is seen to indent the extraforaminal portion of the exiting right L4 nerve root at this level.
There is a posterior disc bulge at the L3-L4 level. Far lateral (extraforaminal) disc bulges are noted bilaterally at the L3-L4 and L5-S1 levels and on the left side at the L4-L5 level.
The L5-S1 facet joints show degenerative changes. Facetal hypertrophy is seen at the L3-L4 and L4-L5 levels.
..2/.
There is ligamentum flavum hypertrophy at the L4-L5, L5, L5-S1 and S1 levels.
The pedicles of the lumbar vertebrae appear congenitally short in their antero-posterior dimensions.
Type II degenerative changes are seen within the superior aspect of the L4 and L5 vertebral bodies.
The visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the L1-L2 level and the thecal sac terminates at the S1 level.
The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :
15.0 mm at L1-L2
13.0 mm at L2-L3
13.0 mm at L3-L4
11.0 mm at L4-L5
10.0 mm at L5-S1.
Incidentally noted is a hypointense signal on the T1 Weighted images in the sacrum, adjacent to the right S. I. joint, anteriorly and inferiorly, which is of ? etiology.
IMPRESSION :
The MRI features are suggestive of :
1. A left paracentral disc herniation at the L5-S1 level with indentation upon the traversing left S1 nerve root which is probably inflamed.
2. A posterior disc herniation at the L4-L5 level.

- 3 - Scan-00008
3. A right far lateral (extraforaminal) disc herniation indenting the extraforaminal portion of the exiting right L4 nerve root at the L4-L5 level.
4. Facetal arthropathy at the L5-S1 level and facetal hypertrophy at the L3-L4 and L4-L5 levels.
5. Ligamentum flavum hypertrophy at the L4-L5, L5, L5-S1 and S1 levels.
6. Congenitally short pedicles of the lumbar vertebrae in their antero-posterior dimensions.
7. Tight canal at the L4-L5 and L5-S1 levels.
