Peripheral CCC. (a) Axial T2w image. In S IV slightly heterogeneous hyperintense lobulated lesion (arrow); cyst (asterisk). (b-c) T1w in- and out-phased images. The lesion appears hypointense. (d–h) In dynamic evaluation after GD-BOPTA administration the nodule appears slightly heterogeneous hypervascular in arterial phase (e) with progressive enhancement in portal and equilibrium phases. After 5′ (h) note persistent enhancement and peripheral wash out. (i) Epatobiliary phase image after 1 h. The lesion appears hypointense, showing central pooling and more evident peripheral wash out (arrowheads).
