Name of the Patient : Abc XyzGalmn / M / 20 yrs.
Referred by : Dr. Abc Xyzngsarkar.
Examination : M.R.I. of the S. I. Joints.
CLINICAL PROFILE :
C/O low back pain on the right side with radiation to the RLE since 2 months.
M.R.I of the S. I. joints was performed using the following parameters :
5 mm thick T1 Weighted and T2 Weighted axial images.
5 mm thick T1 Weighted and STIR coronal images.
The lumbo-sacral spine was screened with 5 mm thick T1 Weighted sagittal images and 5 mm thick T2 Weighted axial images.
There is an ill-defined, hypointense signal on the T1 Weighted images in the right iliac bone adjacent to the right sacro-iliac joint. This lesion appears hyperintense on the T2 Weighted and STIR images. There is no obvious bone erosion or destruction seen. There is slight widening of the right sacro-iliac joint space. The right sacral ala is unremarkable.
A subtle but similar signal intensity change to a much lesser degree, is noted in the left iliac bone, inferiorly, adjacent to the left S. I. joint (scan 106.9). Fatty marrow changes are also noted in the left iliac bone. The left S. I. joint per se is unremarkable. No abnormal soft tissue is noted adjacent to the S. I. joints on either side.
The images of the lumbo-sacral spine reveal small posterior disc bulges at the L4-L5 and L5-S1 levels. Spina bifida is noted at S1.
1. Altered signal in the right iliac bone adjacent to the right S. I. joint may suggest sacroilitis.
2. Similar signal intensity change, but to a lesser degree, is noted in the left iliac bone adjacent to the left S. I. joint.
3. Spina bifida at S1.
