Two left paravertebral ovoid masses, the smaller one seen at left para-aortic region opposite L2/L3 intervertebral disc and the larger one just lateral to the left common iliac artery opposite L5 vertebra, with a third similar ovoid mass at a lower level laterally anterior to the left iliopsoas muscle, representing enlarged pathological lymph nodes.
Altered bone marrow signals are seen at the right iliac bone, showing low signals on T1 WIs and heterogeneous bright signals on T2 WIs and neurography, with bone expansion and cortical breach, exhibiting heterogeneous avid post-contrast enhancement, highly suggestive of aggressive marrow infiltrative lesion.
Another small focus of low signals on T1 & T2 WIs is noted at S1 vertebra.
Degenerative lumbar disc disease.
