Name of the Patient : Abc XyzMehta lmn / F / 33 yrs.
Referred by : Dr. Abc Xyzaubal.
Examination : M.R.I. of the Dorso-lumbar Spine.

CLINICAL PROFILE :

Known C/O Potts spine with psoas abscess since 00.00.00. On AKT.
C/O backache radiating to the LLE with paresthesias and limp.
H/O fever since 2 weeks.

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.

6 mm thick T1 Weighted coronal images.

OBSERVATION :

There is anterior wedging of the L1 vertebral body with mild angular kyphus at that level.

There is replacement of the normal marrow of the D12, L1 and the left antero-lateral margin of the L2 vertebral bodies by hypointense areas on the T1 Weighted images. These are seen to turn heterogeneously hyperintense on the T2 Weighted images. The superior and inferior cortical endplate of the L1 and D12 vertebral bodies are breached with involvement of the D12-L1 intervertebral disc. There is minimal prevertebral soft tissue extension at the D12 and L1 levels. There is bilateral paravertebral soft tissue extension, more on the left side, with involvement of the psoas muscle. The psoas muscle on the left side appears bulky and the lesion is seen to extend into the

pelvis. These lesions are slightly hyperintense to muscle on the T1 Weighted images and turn hyperintense on the T2 Weighted images with presence of septae and would represent abscess formation. Minimal anterior epidural extension is seen at the D12-L1 level.

The rest of the visualized dorso-lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The facet joints are unremarkable.

The visualized dorso-lumbar spinal cord reveals normal signal intensity. There is no cord compression.

The conus medullaris terminates at the L1-L2 level.

Focal fatty marrow change is noted in the L5 body and right pedicle, ?? due to previous infective focus and subsequent healing.

IMPRESSION :

In a known C/O Potts spine, the MRI features are suggestive of altered signal of the D12, L1 and L2 vertebral bodies with involvement of the D12-L1 intervertebral disc with extensions as described. A large left psoas abscess is noted extending from about the D12 vertebral level, into the pelvis.

As compared to the previous MRI dated 00.00.00, there is no significant change noted.
