Name of the Patient : Abc Xyzanu N. Hoolmn / F / 50 yrs.
Referred by : Dr. Abc Xyzankhla.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache.

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 retroplacement of the L5 vertebra over the S1 vertebra.

A posterior disc herniation with peridiscal osteophytes is seen to narrow both neural foramina at the L5-S1 level. There is slight inferior migration of this disc with indentation upon the traversing S1 nerve roots (right more than left). The L5-S1 facet joints show degenerative changes. Ligamentum flavum hypertrophy is noted at this level. This disc appears dessicated.

Posterior disc bulges are noted at the L3-L4 and L4-L5 levels.

The L3-L4 and L4-L5 intervertebral discs show mild loss of water content. There is mild facetal hypertrophy at these levels.

There is anti-clockwise rotation of the upper lumbar vertebrae.


The lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The rest of the facet joints and 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 S2 level.

The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

16.0 mm at L1-L2
17.0 mm at L2-L3
18.0 mm at L3-L4
15.0 mm at L4-L5
11.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. Retroplacement of the L5 vertebra over the S1 vertebra.

2. A posterior disc herniation with peridiscal osteophytes at the L5-S1 level with slight inferior migration of this disc with indentation upon the traversing S1 nerve roots (right more than left).

3. Facetal arthropathy and ligamentum flavum hypertrophy at the L5-S1 level.
