Name of the Patient : Abc Xyzlmn / M / 55 yrs.
Referred by : Dr. Abc Xyzshar / Dr. Abc Xyzatt.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O radicular pain in the LLE with paresthesias with left foot drop.
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 a posterior and a left far lateral disc herniation at the L4-L5 level with anterior indentation of the thecal sac and the extraforaminal portion of the traversing left L4 nerve root. The L4-L5 facet joint on the left side shows mild degenerative change. This disc shows loss of water content.
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 S1-S2 level.
- 2 - Scan-00007
The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :
18.0 mm at L1-L2
19.0 mm at L2-L3
15.0 mm at L3-L4
15.0 mm at L4-L5
13.0 mm at L5-S1.
The dorsal spine was screened with the help of 4 mm thick T2 Weighted sagittal images and which does not reveal any diagnostic feature of note.
The MRI features are suggestive of a posterior and a left far lateral disc herniation at the L4-L5 level indenting the
extraforaminal portion of the traversing left L4 nerve root.
