Left hemi-scrotal poorly defined heterogeneous complex mass lesion of partly cystic and partly solid components the latter shows enhancement in the post-contrast study, the cystic component appears as multilocular.
Left retro-peritoneal mainly para-aortic region huge fairly defined complex heterogeneous mass lesion of partly cystic and partly enhanced solid components, of nearly similar consistency of the aforementioned left testicular mass, is seen abutting the aorta with small pre-aortic and aortocaval components. This mass is seen resting on the left psoas muscle with no invasion, abutting the left renal hilum indenting its surface and displacing the left ureter laterally, superiorly it also exerts mass effect on the surrounding bowel loops and their mesenteric vessels displacing them anterolaterally with no infiltration.
The left renal vein is likely compressed with subsequent dilatation of the left testicular vein and left pelvic varicosities are also seen.
