Name of the Patient : Abc Xyzet Nilmn / M / 35 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with radiation of pain to the LLE with paresthesias since 5 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 mild retroplacement of the L5 vertebra over the S1 vertebra.
A large left paracentral disc herniation with peridiscal osteophytes is seen to compress upon the thecal sac and impinge the traversing left S1 nerve root at the L5-S1 level. A disc portion is seen to lie within the left anterior epidural space at the L5 vertebral level. The L5-S1 intervertebral disc is markedly dessicated.
A small posterior disc herniation with peridiscal osteophytes is seen to indent the thecal sac and narrow both neural foramina at the L4-L5 level. This intervertebral disc shows mild loss of water content.
There is mild facetal hypertrophy at the L4-L5 and L5-S1 levels.
A focal hyperintensity on all the pulse sequence is seen within the L3 vertebral body on the left side and this may represent a hemangioma with fat content.
- 2 - Scan-00009
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-L2 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 :
18.0 mm at L1-L2
18.0 mm at L2-L3
16.0 mm at L3-L4
13.0 mm at L4-L5
8.0 mm at L5-S1.
The cervico-dorsal spine was screened with the help of 5 mm thick T2 Weighted sagittal images which does not reveal any diagnostic feature of note.
The MRI features are suggestive of :
1. A large left paracentral disc herniation with peridiscal osteophytes, impinging the traversing left S1 nerve root at the L5-S1 level with a disc portion lying within the left anterior epidural space at the L5 vertebral level.
2. A small posterior disc herniation with peridiscal osteophytes at the L4-L5 level.
