Figure 2. A 72-year-old female with alcohol-related cirrhosis presenting with a 1.2 cm LR 5 observation in the caudate lobe (A). The patient underwent SBRT after a multidisciplinary discussion. 3 months post SBRT, there is a small focal area of nonenhancement centrally, LR TR Nonviable (B). Note the surrounding arterial phase hyperenhancment in the parenchyma, compatible with radiation changes. 6 months post SBRT, there is no enhancement, LR-TR Nonviable (C). In addition, there are improving geographic radiation changes within the surrounding parenchyma. At 12 months post SBRT, there is a new mass-like area of enhancement along the margin, LR-TR Viable (D).
