Name of the Patient : Abc Xyzo Dhulmn / M / 51 yrs.
Referred by : Dr. Abc Xyzhari.
Examination : M.R.I. of the Sacrum.
CLINICAL PROFILE :
C/O backache radiating to the LLE with paresthesias since 1 1/2 months.
M.R.I of the sacrum was performed using the following parameters :
5 mm thick T1 Weighted and T2 Weighted sagittal images.
6 mm thick T1 Weighted and T2 Weighted axial images.
4 mm thick T1 Weighted and STIR coronal images.
The S1, S2 and S3 sacral segments appear hypointense on the T1 Weighted images and heterogeneously hyperintense on the T2 Weighted images. The ala of the sacrum are also involved bilaterally. There is an intermediate signal intensity soft tissue lesion on the T1 Weighted images in the presacral region, which appears hyperintense on the T2 Weighted images. This soft tissue lesion is more on the left side and extends upto the posterior margin of the left psoas muscle. There is also extension of the soft tissue lesion into the sacral canal with thecal sac compression in the upper sacral region and obliteration of the sacral foramina bilaterally. Irregularity of the margins of the sacro-iliac joint per se is also noted with probable involvement of the left sacro-iliac joint. The S1-S2 intervertebral disc appears unremarkable. There is probable involvement of the iliac wings bilaterally.
Small posterior disc herniations with peridiscal osteophytes are noted at the L2-L3, L3-L4 and L4-L5 levels.
The visualized lumbar vertebral bodies reveal normal signal intensity.
Altered signal of the S1, S2 and S3 sacral segments, with presacral and intraspinal soft tissue lesion as described is not specific for a single etiology. A neoplastic process like a round cell tumor is a likely possibility.
The possibility of an infective etiology (tuberculosis) seems less likely.
