Fig. 2.

(A) Sagittal T2-weighted image of the pelvis, (B) sagittal T1-weighted fat saturated image and (C) Contrast-enhand sagittal T1-weighted fat saturated image showed tumor extending from the extraperineal (thin white arrow(C)) into the pelvis (thin blue arrow (C)). The mass demonstrates marked enhancement and has internal low-intensity “swirled” signal on all image sequences. Adjacent structures, including the urinary bladder (curved arrows) and uterus (thick arrow), are shifted to the anterior but are not invaded by the tumor.
