The targetoid appearance (TA) due to the fibrous stroma in the center of the ICC appears as a central area of less intensity, compared to a more hyperintense peripheral area on T2-W sequences (A) and DWI (B). The presence of this central fibrous stroma also characterizes the behaviour during the dynamic study. On dynamic contrast study, the mass-forming ICCS showed prominent peripheral rim enhancement (C: arterial phase) with centripetal or gradual progressive enhancement (D: delayed phase)
