Treatment of an anterior left renal tumour in close proximity with a bowel loop. a CT performed the day of treatment showing the close proximity of the tumour to be treated (white arrow) with a bowel loop (asterisks). Note the external compression to obtain the desired position of the patient for an easy access to the target tumour. b multiplanar reconstruction of the CT images showing the close proximity of the tumour (white arrow) with a bowel loop (asterisks). c A CT scan performed after fluid (hash) injection confirmed the correct displacement of the colon (asterisks) from the target tumour (white arrow) (arrowhead = spinal needle). d CT scan demonstrating the insertion of the microwave antenna (arrowhead) into the renal tumour (white arrow). e Contrast-enhanced CT performed immediately after treatment demonstrating the complete ablation of the renal tumour (white arrow) without complications
