Acute Kidney Failure in a Young African American Male

Figure 2

Abdomen and pelvis computed tomogram with intravenous contrast revealed mild bilateral hydroureteronephrosis with point of obstruction at the level of distal abdominal aorta and inferior vena cava. There was an ill-defined, infiltrative soft tissue mass encasing both aorta and IVC (approximately 7.2 cm). The mass appeared to infiltrate along the bilateral proximal common iliac vessels.
