Ventrodorsal fluoroscopic image of a 14-year-old, 6.4 kg, neutered male, miniature pinscher diagnosed with renal cystadenocarcinoma of the right kidney. Intravenous contrast was injected percutaneously through a pigtail catheter to confirm its location and that the entirety of contrast remains within the ICL with no extracapsular leakage.
