Figure 2 Case 2. A: Multi-phase computed tomography scan: a hypodense area, indicated by the white arrow, in the liver during the arterial phase post trans-arterial chemo-embolization treatment; B: Positron emission tomography scan: in the same area, there is avid fludeoxyglucose uptake, indicating residual tumor.
