Name of the Patient : Abc Xyzlmn / M / 37 yrs.
Referred by : Dr. Abc Xyznghal.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O imbalance towards the right side with incontinence of urine (few drops) since 6-7 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.
6 mm thick T1 Weighted and T2 Weighted axial images.
There is slight loss of water content of the L2-L3 disc.
There is seen an approximately 1.3 x 0.9 x 5.2 cms sized well-defined intradural mass lesion in the spinal canal centrally extending over the L1 and L2 vertebral levels. This lesion is nearly isointense to normal cord on the T1 Weighted images, but appears hyperintense on the T2 Weighted images. The intraspinal nerve roots are displaced peripherally by the lesion. The tip of the conus medullaris is seen separately from the lesion.
Minimal posterior disc bulges are noted at the L4-L5 and L5-S1 levels with slight left neural foraminal narrowing at the L4-L5 level.
Schmorls node is seen superior to the L3 vertebral body.
The lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the D12 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 :
16.0 mm at L1-L2
16.0 mm at L2-L3
16.0 mm at L3-L4
14.0 mm at L4-L5
12.0 mm at L5-S1.
The dorsal spine was screened with the help of 4 mm thick T1 Weighted sagittal images, which does not reveal any diagnostic feature of note.
An approximately 1.3 x 0.9 x 5.2 cms sized intradural mass lesion in the spinal canal, extending over the L1 and L2 vertebral levels as described, is not specific for a single etiology. An ependymoma or a nerve sheath tumor are likely possibilities.
