Name of the Patient : Abc Xyzben Gorlmn / F / 74 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Sacro-iliac Joints.

CLINICAL PROFILE :

C/O backache and pain in the left hip region.
Alleged H/O fall +.

EXAMINATION :

M.R.I of the sacro-iliac joints was performed using the following parameters :

5 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.

5 mm thick T1 Weighted and STIR coronal images.

The lumbar spine was screened with 5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is an ill-defined, hypointense signal on the T1 Weighted images in the sacral and iliac bones adjacent to the left sacro-iliac joint. This signal appears hyperintense on the T2 Weighted and STIR images. Slight widening of the left sacro-iliac joint space is noted and a hyperintense signal on the T2 Weighted and STIR images is noted in the left sacro-iliac joint space. The cortical margins of the left sacro-iliac joint are not well defined. No significant soft tissue extension of this lesion is noted.

The rest of the visualized bones of the pelvis shows spotty fatty marrow changes. The right sacro-iliac joint is otherwise unremarkable. Slight effusion is seen within the visualized hip joints.
>
Slight widening (diastasis) of the symphysis pubis is noted.

Screening, images of the lumbar spine reveal small posterior disc herniations at the L3-L4, L4-L5 and L5-S1 levels and Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra.

IMPRESSION :

Altered signal in the sacral and iliac bones adjacent to the left sacro-iliac joint with slight widening of the left sacro-iliac joint space and irregularity of the margins of the left sacro-iliac joints as described suggests left sided sacro-ilitis.
