Name of the Patient : Abc Xyzh lmn / M / 16 yrs.
Referred by : Dr. Abc Xyzosale.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to BLE (right more than left) since 6 months.
Also C/O epilepsy since the age of 13 years with MR.

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.

IMAGES SHOW PATIENT MOTION INSPITE OF SEDATION. SCAN WAS REPEATED AGAIN ON 00.00.00 BUT STILL IMAGES SHOWED PATIENT MOTION.

OBSERVATION :

There is a change in the alignment of the L5 over the S1 vertebra.

There is Grade II spondylolisthesis of the L5 over the S1 vertebra without obvious spondylolysis. A large pseudo-posterior disc herniation is seen at the L5-S1 level with anterior compression of the thecal sac and canal stenosis. There is bilateral neural foraminal narrowing with indentation upon the foraminal portion of the L5 nerve roots bilaterally. This intervertebral disc shows loss of water content.

A postero-central and right postero-lateral disc bulge is noted at the L4-L5 level with anteior indentation of the thecal sac and right neural foraminal narrowing.

The lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
..2/.




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 :

19.0 mm at L1-L2
18.0 mm at L2-L3
16.0 mm at L3-L4
12.0 mm at L4-L5
6.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. Grade II spondylolisthesis of the L5 over the S1 vertebra without obvious spondylolysis.

2. A large pseudo-posterior disc herniation at the L5-S1 level with indentation upon the foraminal portion of the L5 nerve
roots bilaterally and canal stenosis.
