Name of the Patient : Abc Xyza Halmn / F / 62 yrs.
Referred by : Dr. Abc Xyzauhan.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with pain radiating to the LLE with paresthesias since 1 year.
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 appears to be sacralization of the L5 vertebra and the L1 vertebra is as marked on the film. The lumbar intervertebral discs show loss of water content.
Postero-central, left postero-lateral and left far lateral disc herniations are seen at the L4-L5 level. There is indentation upon the traversing left L5 nerve root and the foraminal and extraforaminal portion of the exiting left L4 nerve root. Also seen is indentation upon the thecal sac and left neural foraminal narrowing at this level.
Postero-central and right postero-lateral disc herniations are seen to indent the thecal sac and narrow the right neural foramen respectively at the L3-L4 level.
Small right far lateral disc bulges are noted at the L3-L4 and L4-L5 levels.
Scan-00006
Small posterior peridiscal osteophytes are noted at the L3-L4 and L4-L5 levels.
The L2-L3, L3-L4 and L4-L5 facet joints show mild degenerative changes.
Anterior disc herniations are noted at the L3-L4 and L4-L5 levels.
A focal hypointensity on all the pulse sequences is seen within the L2 vertebral body on the right side (? bone island).
The rest of the lumbar vertebral bodies reveal normal signal intensity. The remaining facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the L1 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
15.0 mm at L2-L3
14.0 mm at L3-L4
12.0 mm at L4-L5
9.0 mm at L5-S1.
IMPRESSION :
1. Sacralization of the L5 vertebra and the L1 vertebra is as marked on the film.

2. Postero-central, left postero-lateral and left far lateral disc herniations with indentation upon the traversing left L5 nerve root and the foraminal and extraforaminal portion of the exiting left L4 nerve root at the L4-L5 level.
3. Postero-central and right postero-lateral disc herniations at the L3-L4 level.
