There is left renal hilar ill-defined heterogeneous soft tissue mass lesion is seen overlying left renal hilum and extending laterally engulfing renal capsule and along perinephric planes, it is also seen encasing its vascular pedicle extending medially encasing the aorta and peri-aortic space, this soft tissue mass lesion is seen creeping along the renal pelvis and uppermost ureteric segment with subsequent compromise and consequently left moderate renal backpressure changes, associated blurring of the perirenal fat planes is also noted.
This soft tissue mass lesion shows mild enhancement and is seen encasing the renal vein that appears attenuated, yet still, patent as well as encasing patent renal artery with no invasion detected.
Moreover, multiple discrete and matted para-aortic lymph nodes are also seen, the largest at the left para-aortic group.
