Name of the Patient : Abc Xyzg Dlmn / M / 8 yrs.
Referred by : Dr. Abc Xyzdar.
Examination : M.R.I. of the Dorso-lumbar Spine.
CLINICAL PROFILE :
C/O mark in the mid back since birth.
M.R.I of the dorso-lumbar spine was performed using the following parameters :
4 mm thick T1 Weighted and T2 Weighted sagittal images.
5 mm thick T1 Weighted and T2 Weighted axial images.
Segmentation anomalies are seen in the dorso-lumbar region with clockwise rotation of these vertebrae with a congenital block vertebra at the L2-L3 level, with spina bifida at the L2 and L3 levels and an open spinal canal, posteriorly.
Two hemicords are seen within the thecal sac over the D9 to L1 vertebral levels. The right hemicord is smaller in size and is probably attached to the lamina on the right side at the L1 level. A syrinx (isointense to CSF) is seen within the left hemicord at the D9 vertebral level and in the united cord at the D8 vertebra.
The conus medullaris is seen to terminate at the L4-L5 level.
A lesion which is near isointense to CSF on all the pulse sequences is seen within the spinal canal at the S3 vertebral level and may represent a cyst (? dermoid cyst). The filum is seen to be attached to the superior aspect of this cyst.
The visualized dorso-lumbar vertebral bodies and intervertebral discs reveal normal signal intensity.
The MRI features are suggestive of diastematomyelia with tethering of the cord as described.
