Preoperative computed tomography after application of intravenous contrast substance of a child following induction chemotherapy with persistent vascular encasement of major abdominal arteries by neuroblastoma

Borders of the tumor (starlets) and expected working space as a multiple of the aortal diameter (arrows) required to see the tumor margin at the level of the (a) coeliac trunk, (b) superior mesenteric artery, (c) right renal artery, (d) left renal vein. The circle depicts the desired circular maximum working space from the center of the landmark vessel equaling a radius of 3x the diameter of the aorta (working space score 3)
