case_images: Selective angiography of the splenic artery. Selective contrast-enhanced angiography of the splenic artery and side branches, pre-fiducial marker placement (A) and post-fiducial marker placement (B). The red arrows show the catheter in the splenic artery. The blue arrow shows the first fiducial placed in a splenic artery side branch.

case_images: Computed tomography before and after fiducial placement. Contrast-enhanced axial and coronal computed tomography scans of the abdomen pre-fiducial marker placement (A-B), post-fiducial marker placement (C-D), and the last follow-up control scan (E-F). The red arrows show the lesion, next to the ablation cavity. The blue arrows show the fiducial markers in the spleen.
