Name of the Patient : Abc Xyz Almn / M / 19 yrs.
Referred by : Dr. Abc Xyzaj.
Examination : M.R.I. of the Dorso-lumbar Spine.

CLINICAL PROFILE :

Known C/O potts spine. Transthoracic decompression of D9 and D10 was done on 00.00.00.
C/O backache with slight weakness of the RLE since 1 year.

EXAMINATION :

M.R.I of the dorso-lumbar 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.

OBSERVATION :

There is still seen destruction and collapse of the D10 and D11 vertebral bodies with partial destruction of the D12 vertebra and angular kyphus at that level. The superior and inferior cortical endplates of the D12 and D10 vertebrae and both endplates of D11 are breached with involvement of the D10-D11 and D11-D12 intervertebral discs.There is replacement of the normal marrow by hypointense areas on the T1 Weighted images of the L1, D12, D11, D10, D9 and D8 vertebral bodies on the T1 Weighted images. These are seen to turn heterogenously hyperintense on the T2 Weighted images. There is pre and paravertebral soft tissue extension over the D8 to D12 vertebral levels. This lesion is hyperintense to normal muscle but hypointense to fat on the T1 Weighted images and turns hyperintense on the T2 Weighted images and most probably represents an abscess. The costo-vertebral and costo-transverse joints at the D9-D10, D10-D11 and D11-D12 levels are involved by the pathology. The pedicles of the D10, D11 and D12 vertebrae are also involved. Anterior and lateral epidural lesion is seen

over the D10 and D11 levels with anterior compression of the cord. The spinal cord at the D10-D11 level shows a subtle hyperintense signal on the T2 Weighted images and which is isointense to cord on the T1 Weighted images and represents cord edema/ischemia/myelitis.
Suspectibility artifacts are noted in the D11 vertebral body on the right side.

The rest of the visualized dorsal vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The conus medullaris terminates at the L1 level.IMPRESSION :
The patient is now status post-oprative (exact details not available).

In a known C/O Potts spine, the MRI features are suggestive of altered signal of the L1, D12, D11, D10, D9 and D8 vertebrae with a large anterior and lateral epidural lesion over the D10 and D11 levels compressing the cord anteriorly and altered signal of the spinal cord at the D10-D11 level represents cord edema/ischemia/myelitis.
As compared to the previous MRI (scan no.0000) dated 00.00.00
there is reduction in the size of the pre and paravertebral abscess as well as the epidural extension.
