title: Asymptomatic Renal Pseudoaneurysm Following Laparoscopic Partial Nephrectomy.
abstract: A 66-year-old-woman underwent a laparoscopic left partial nephrectomy for a 3 cm partially exophytic tumor arising from the posterior interpolar region of the left kidney. Follow-up surveillance computed tomography 6 months following the surgery found an incidental 4 cm lesion in the left kidney that is avidly enhanced in the arterial phase, consistent with a renal pseudoaneurysm. She was completely asymptomatic. Renal pseudoaneurysm is a rare complication following minimally invasive nephron-sparing surgery and typically presents in the early postoperative period with gross hematuria. However, a large renal pseudoaneurysm may also present as an asymptomatic incidental finding and is amenable to angioembolization.
