Name of the Patient : Abc Xyz N. lmn / F / 34 yrs.
Referred by : Dr. Abc Xyznna.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with pain radiating to BLE since 3 years.
Alleged H/O fall 2 1/2 years ago.
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.
There are mild posterior disc bulges at the L4-L5 and L5-S1 levels.
The lumbar vertebral bodies and 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-L1 level and the thecal sac terminates at the S1-S2 level.
The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :
17.0 mm at L1-L2
17.0 mm at L2-L3
15.0 mm at L3-L4
13.0 mm at L4-L5
14.0 mm at L5-S1.

The sacro-iliac joints were assessed with 5 mm thick T1 Weighted and STIR coronal images which shows subtle hypointense areas replacing the normal marrow of the sacral and the iliac bones adjacent to the right sacro-iliac joint on the T1 Weighted images. These are seen to turn hyperintense on the STIR images. The right sacro-iliac joint per se is normal. The left sacro-iliac joint per se is unremarkable. However fatty changes are seen within the bones adjacent to this joint.
No significant abnormality is detected within the lumbar spine on this study.
Altered signal in the sacral and the iliac bones adjacent to the right sacro-iliac joint is probably inflammatory (? seronegative spondyloarthropathy ?? infective) in etiology.
