Axial CT in late arterial phase (AP) obtained (a) pretreatment: image shows nonrim arterial phase hyperenhancement (APHE) of a 2-cm LR-4 observation in segment II-III (arrow). b 2 months post percutaneous ethanol ablation (PEA): image shows interval growth (arrow) and a new LR-4 observation (arrowhead) in segment VIII. At this point, the treated lesion is categorized LR-TR viable. c Axial T1-weighted subtraction MR in late AP obtained 1 month post repeat PEA: image shows serpiginous enhancement in the location of the treated lesion possibly representing vascular fistula. The treated observation is categorized LR-TR Equivocal
