title: Local recurrence of renal cell carcinoma that simulated multiple renal arteriovenous fistulas after laparoscopic partial nephrectomy: Report of a rare case.
abstract: Herein we report a patient who was initially thought to have renal arteriovenous fistulas 3 months after laparoscopic partial nephrectomy for a small renal mass. After timely intervention using selective renal artery embolization, computed tomography 9 months post-surgery showed persistent renal arteriovenous fistulas and nodular lesions in the perirenal fat. The patient then underwent radical nephrectomy, and histopathological examination showed underlying recurrent clear cell renal cell carcinoma invading the intraparenchymal arteries and veins, which was simulating multiple high-flow renal arteriovenous fistulas.
