case_images: The morning of surgery, he underwent coil placement by IR; a 2 x 5 mm platinum embolization coil was percutaneously deployed under CT guidance into the center of the tumor through a 22-gauge x20-cm Chiba needle (Fig. 2).
case_images: (a) Intracorporeal laparoscopic ultrasound demonstrating metal coil within indistinct, endophytic, isoechoic renal mass. Dashed arrows: area of suspected endophytic mass along medial aspect of the upper pole; Black arrow: ultrasound probe; White arrow: hyperechoic changes and artifact of metallic coil on ultrasound. (b) Capsular marking of anticipated tumor excision borders, marked with cautery using laparoscopic ultrasound as a guide. Arrows outline marking.

case_images: However, when laparoscopic ultrasound was performed, the intratumoral coil could be visualized by the metallic artifact on the ultrasonic image (Fig. 3a). Intended lines of resection were marked on the capsule (Fig. 3b).
