Name of the Patient : Abc Xyzth Slmn / M / 27 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with pain radiating to the LLE with paresthesias since 10 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.
There is sacralization of the L5 vertebra and L2 vertebral body is as marked on the film. There is mild retroplacement of the L3 over the L4 and L4 over the L5 vertebrae.
Large left paracentral and left postero-lateral disc herniations are seen at the L3-L4 level with compression of the thecal sac and left neural foraminal narrowing. There is inferior migration of the disc in the left lateral recess of the L4 vertebral body with impingement of the traversing left L4 nerve root.
A posterior disc herniation is noted at the L4-L5 level with anterior indentation of the thecal sac. Slight inferior migration of the disc is seen. The L3-L4 and L4-L5 intervertebral discs show loss of water content.
Facetal and ligamentum flavum hypertrophy is seen at the L3-L4 and L4-L5 levels.
The lumbar vertebral bodies show hypointense signal on the T1 Weighted images and this may represent preponderance of
haematopoietic marrow (? anemic).
- 2 - Scan-00002
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 D12 level and the thecal sac terminates at the L5 level.
The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :
17.0 mm at L1-L2
15.0 mm at L2-L3
11.0 mm at L3-L4
10.0 mm at L4-L5
9.0 mm at L5-S1.
1. Sacralization of the L5 vertebra.
2. Large left paracentral and left postero-lateral disc herniations at the L3-L4 level with inferior migration of the disc in the left lateral recess of the L4 vertebral body impinging the traversing left L4 nerve root.
3. A posterior disc herniation at the L4-L5 level with slight inferior migration of the disc.
