Lymphoma, RPF, and hydronephrosis on CT

A CT scan in axial projection (A) shows stranding (arrow) to the left of the aorta (asterisk) associated with left hydronephrosis (arrowhead). Bulky soft tissue lymphomatous nodes (short arrow) compress the IVC (dashed arrow). Image B shows the strand-like RPF (arrows) surrounding the vessels and the obstructed left ureter (arrowhead).
