Name of the Patient : Abc Xyzrlal Chudalmn / M / 60 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the RLE with paresthesias since 8 months.
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.
FEW IMAGES SHOW PATIENT MOTION.
All the lumbar intervertebral discs show loss of water content.
A right postero-lateral and bilateral far lateral disc herniations with small peridiscal osteophytes is seen to narrow the right neural foramen and indent the exiting right L5 nerve root at the L5-S1 level. Mild ligamentum flavum hypertrophy is noted at this level.
A posterior disc extrusion, more to the right of the midline is seen to indent the thecal sac and narrow the neural foramina bilaterally at the L4-L5 level. There is superior migration of the disc posterior to the L4 vertebral body. The facet joints at this level show hypertrophic degenerative changes with effusion. Also seen is ligamentum flavum hypertrophy at this level.
A left postero-lateral and far lateral disc herniation is seen to narrow the left neural foramen and indent the exiting left L3 nerve root at the L3-L4 level.
A postero-central disc herniation is seen to indent the thecal sac at the L1-L2 level. There is slight superior migration of a disc portion.
There are bilateral far lateral disc herniations (extraforaminal) at the L4-L5 level.
The L2-L3, L3-L4 and L5-S1 facet joints show degenerative changes.
Incidental note is made of a left renal cyst.
The lumbar vertebral bodies 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 D12 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 :
12.0 mm at L1-L2
15.0 mm at L2-L3
13.0 mm at L3-L4
9.0 mm at L4-L5
11.0 mm at L5-S1.

1. Right postero-lateral and far lateral disc herniation with small peridiscal osteophytes indenting the exiting right L5 nerve root at the L5-S1 level with mild ligamentum flavum hypertrophy.
2. A posterior disc extrusion, more to the right of the midline at the L4-L5 level with superior migration of the disc with hypertrophic facetal arthropathy and ligamentum flavum hypertrophy with canal stenosis.
3. A postero-central disc herniation at the L1-L2 level with slight superior migration of the disc portion.
