Name of the Patient : Abc Xyzlmn / F / 28 yrs.
Referred by : Dr. Abc Xyzvade.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the LLE since 3 years which has increased since 10 days.
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.
There is sacralization of the L5 vertebra and the L3 vertebral body is as marked on the film.
There is mild retroplacement of the L4 over the L5 vertebra.
A large left paracentral disc extrusion is seen at the L4-L5 level with left antero-lateral compression of the thecal sac and resultant tight canal. An extruded disc portion is seen to migrate inferiorly in the left lateral recess of the L5 vertebra with impingement of the traversing left L5 nerve root. This disc is dessicated. Mild ligamentum flavum hypertrophy is also seen at the L4-L5 level.
The lumbar vertebral bodies and the remaining intervertebral discs show normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the D12-L1 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 :
20.0 mm at L1-L2
19.0 mm at L2-L3
17.0 mm at L3-L4
9.0 mm at L4-L5
13.0 mm at L5-S1.
The sacro-iliac joints were screened with 6 mm thick T1 Weighted coronal images and these show no feature of note.
Degenerated L4-L5 intervertebral disc with a large left paracentral disc extrusion at this level with an extruded disc portion seen to migrate inferiorly in the left lateral recess of the L5 vertebra with impingement of the traversing left L5 nerve root
and resultant tight canal at this level.
