Name of the Patient : Abc Xyzl Dslmn / M / 40 yrs.
Referred by : Dr. Abc Xyzstonji.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O radicular pain to the LLE.
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 large left paracentral disc extrusion at the L4-L5 level with posterior peridiscal osteophytes causing left antero-lateral indentation of the thecal sac. Inferior migration of the disc is seen into the left lateral recess of the L5 vertebra with impingement of the traversing left L5 nerve root.
A postero-central disc herniation with peridiscal osteophytes is noted at the L5-S1 level.
Small postero-central disc herniations with peridiscal osteophytes are seen at the L1-L2 and L3-L4 levels.
The L1-L2, L3-L4, L4-L5 and L5-S1 intervertebral discs show loss of water content. The L5-S1 disc is reduced in height.
Fat is noted in the filum terminale over the L2-L3 to L4 levels (? a normal variant).
The L4-L5 facet joints show degenerative change, right more than left.
Type II degenerative changes are seen 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 :
17.0 mm at L1-L2
19.0 mm at L2-L3
15.0 mm at L3-L4
11.0 mm at L4-L5
13.0 mm at L5-S1.
The hip joints were screened with 5 mm thick T1 Weighted coronal images and which do not reveal any diagnostic feature of note.
1. A large left paracentral disc extrusion at the L4-L5 level with posterior peridiscal osteophytes and inferior migration of the disc in the left lateral recess impinging the traversing left L5 nerve root.
2. Small postero-central disc herniations with peridiscal osteophytes at the L1-L2 and L3-L4 levels.
