Name of the Patient : Abc Xyzkash Panlmn / M / 58 yrs.
Referred by : Dr. Abc Xyzlkarni.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with pain radiating to the LLE with paresthesias.
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.
The L4-L5 and L5-S1 intervertebral discs show loss of water content.
A posterior disc herniation is seen at the L4-L5 level with anterior indentation of the thecal sac. A free fragment is noted in the left lateral recess at the L5 vertebral level(se/im104/7) with impingement of the traversing left L5 nerve root. The L4-L5 facet joints show degenerative changes. Ligamentum falvum hypertrophy is noted at the L5 level.
There is a postero-central disc herniation with peridiscal osteophytes at the L5-S1 level and anterior indentation of the thecal sac. Bilateral far lateral disc bulges are seen at this level with mild indentation upon the extraforaminal portions of the L5 nerve roots. The L5-S1 facet joint on the left side shows degenerative changes. This disc appears reduced in height.

Type II degenerative changes are noted in the L5 and S1 vertebral bodies adjacent to the L5-S1 disc.
The rest of 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 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 :
18.0 mm at L1-L2
18.0 mm at L2-L3
17.0 mm at L3-L4
13.0 mm at L4-L5
12.0 mm at L5-S1.
1. A posterior disc herniation at the L4-L5 level with a free fragment in the left lateral recess of L5 impinging the traversing L5 nerve roots.
2. A postero-central disc herniation with peridiscal osteophytes at the L5-S1 level with bilateral far lateral disc bulges at this level with mild indentation upon the extraforaminal portion of the L5 nerve roots.
