Name of the Patient : Abc Xyzr R. Shlmn / F / 25 yrs.
Referred by : Dr. Abc Xyziwari / Dr. Abc Xyzheth.
Examination : M.R.I. of the Sacro-iliac joints.
CLINICAL PROFILE :
C/O backache with pain radiating to the LLE since 6-7 months.
M.R.I of the S. I. 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.
There is an ill-defined, hyperintense signal on the T2 Weighted and STIR images in the sacral and iliac bones adjacent to the left sacro-iliac joint. This lesion appears hypointense to the normal marrow on the T1 Weighted images. Probable erosion of the articular margins of the sacrum on the left with involvement of the left sacro-iliac joint is noted. No obvious soft tissue extension of the lesion is identified.
The visualized right sacro-iliac joint is unremarkable.
Screening T1 Weighted sagittal images of the lumbar spine, reveal a small postero-central protruded disc at the D12-L1 level.
Altered signal in the sacral and iliac bones adjacent to the left sacro-iliac joint with involvement of the left sacro-iliac joint per se is not specific for a single etiology.
The differential diagnosis would include,
1. An infective etiology ? tuberculous.
2. Neoplasia like round cell tumor.
