Name of the Patient : Abc XyzAntlmn / F / 38 yrs.
Referred by : Dr. Abc Xyzwhale.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the LLE with paresthesias since 2 1/2 years.
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 Grade I spondylolisthesis of the L4 vertebra over the L5 vertebra. Also seen is a break of the pars interarticularis of the L4 vertebra bilaterally.
A pseudoposterior disc bulge is seen to indent the thecal sac and narrow both neural foramina bilaterally at the L4-L5 level.
Type II degenerative changes are seen within the L5 vertebral body adjacent to the L4-L5 intervertebral disc.
The remaining lumbar vertebral bodies and the intervertebral discs reveal normal signal intensity. 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 :
16.0 mm at L1-L2
17.0 mm at L2-L3
17.0 mm at L3-L4
16.0 mm at L4-L5
11.0 mm at L5-S1.
The MRI features are suggestive of Grade I spondylolisthesis of the L4 vertebra over the L5 vertebra with spondylolysis of the L4 vertebra bilaterally.
