Figure 3.
64-year-old asymptomatic woman with a history of stage IIIA ICC incidentally discovered during an ultrasound examination. (a) Contrast-enhanced T1-weighted gradient-echo sequence in the portal-venous phase shows a large, enhancing lesion centrally located in segment 8 of the liver (arrow). (b) DSA clearly identifies the lesion (arrow). However, this lesion was not visible on both early- (c) and delayed-phase (d) CBCT due to severe streak artifacts caused by an artificial mitral valve (white arrowheads) and only perfusion inhomogeneity of the healthy liver parenchyma in close proximity to the lesion was visualized (black arrowheads).
