A 66-year-old-woman underwent a laparoscopic left partial nephrectomy for 3cm partially exophytic tumour arising from the posterior interpolar region of the left kidney. Follow-up surveillance computed tomograph 6-months following the surgery found an incidental 4cm lesion in the left kidney which avidly enhanced in the arterial phase, consistent with a renal pseudoaneurysm. She was completely asymptomatic. Renal pseudoaneurysm is rare complication following minimally invasive nephron sparing surgery and typically presents in the early post-operative period with gross haematuria. However, a large renal pseudoaneurysm may also present as an asymptomatic incidental finding and is amenable to angioembolization.
