Name of the Patient : Abc Xyz Ralmn / F / 9 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
Alleged H/O fall 1 month ago.
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.
The L5 vertebra is as marked on the film.
There is spondylolysis of the L4 vertebra, bilaterally, with minimal forward translation of the L4 over the L5 vertebra.
The marrow of the visualized dorso-lumbo-sacral vertebral bodies show a predominant hypointense signal on all pulse sequences near the vertebral endplates. No obvious bone erosion or destruction is noted.
The lumbar intervertebral discs reveal normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
There is an ill-defined, hyperintense signal on the T2 Weighted images in the posterior paraspinal muscles bilaterally at the L4 and L5 levels. This may be due to inflammatory changes due to the spondylolysis or may be due to previous trauma.
The conus medullaris terminates at the 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 :
17.0 mm at L1-L2
16.0 mm at L2-L3
16.0 mm at L3-L4
18.0 mm at L4-L5
12.0 mm at L5-S1.
1. The L5 vertebra is as marked on the film.
2. Spondylolysis of the L4 vertebra, bilaterally, with minimal forward translation of the L4 over the L5 vertebra.
3. Altered signal in the visualized dorso-lumbo-sacral vertebrae may suggests a bone dysplasia.
