Name of the Patient : Abc XyzIlmn / M / 51 yrs.
Referred by : Dr. Abc Xyz Sane.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with radiation of pain to the LLE with paresthesias.
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 anterior wedging of the L1 vertebral body.
A posterior disc herniation is seen to indent the thecal sac and narrow both neural foramina at the L4-L5 level. There is mild facetal hypertrophy at this level.
There is a left postero-lateral disc protrusion narrowing the left neural foramen at the L3-L4 level. A left far lateral disc bulge is also noted at the L3-L4 level.
The L1-L2, L4-L5 and L5-S1 intervertebral discs show loss of water content.
The lumbar vertebral bodies show areas of fatty replacement of normal marrow. The rest of the intervertebral discs reveal normal signal intensity. The remaining facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
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 :
14.0 mm at L1-L2
14.0 mm at L2-L3
13.0 mm at L3-L4
9.0 mm at L4-L5
13.0 mm at L5-S1.
The cervico-dorsal spine was screened with 4 mm thick T2 Weighted sagittal images. Posteriorly bulging discs are noted in the cervical region.
The MRI features are suggestive of :
1. Anterior wedging of the L1 vertebral body which may be a result of previous trauma.
2. A posterior disc herniation and mild facetal hypertrophy with a tight canal at the L4-L5 level.
