A 59-year-old man with a renal mass in the right kidney. A Supine dynamic CT image (arterial phase) before biopsy shows a 1.1 cm mass (arrow). B Prone CT fluoroscopy image with contrast medium during biopsy shows needle (arrowhead) penetration of the target mass (arrow). This mass is histologically diagnosed as clear cell RCC. C Selective renal angiography 78 days after biopsy shows AVF (arrow). D Selective renal angiography after coil embolization (arrow) shows the disappearance of AVF
