Name of the Patient : Abc Xyzndra Palmn / M / 22 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to BLE with paresthesias since 1 year.
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.
4 mm thick T1 Weighted coronal images.
There is a well-defined intradural-extramedullary mass lesion at the L3 and L4 vertebral levels which measures approximately 3.2 x 2.0 x 1.5 cms. This lesion is iso to hyperintense to the cord on the T1 Weighted images and turns hyperintense on the T2 Weighted images. The roots appear adherent to this lesion.
A small hyperintense lesion is noted just inferior to the above mentioned lesion on the T1 Weighted images and follows fat signal intensity.
Hyperintense signal is seen at the S3 level on the T1 Weighted images and follows fat signal intensity characteristics on all the pulse sequences. This would represent a lipoma of the filum terminale.
- 3 - Scan-00009
The lumbar vertebral bodies and the intervertebral discs reveal normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
A perineural cyst is seen at the S3 level.
The MRI features are suggestive of an intradural extramedullary lesion measuring approximately 3.2 x 2.0 x 1.5 cms. at the L3 and L4 vertebral levels.
The possibilities to be considered are :
1. Congenital tumors like dermoid/epidermoid.
2. Nerve sheath tumor like neurofibroma.
