Magnetic resonance imaging findings of carcinoma arising from anal fistula: A retrospective study in a single institution

Figure 2 Magnetic resonance images of a 52-year-old woman with adenocarcinoma. A: Axial T1-weighted magnetic resonance imaging; B: Axial T2WI; C: Axial fat-suppressed T2-weighted magnetic resonance imaging (FS-T2WI); D: Sagittal FS-T2WI images show the tumor to the right (orange arrows). The tumor is oval and hyperintense on FS-T2WI without capsule. E-H: Axial dynamic contrast-enhanced images show persistent heterogeneous enhancement (orange arrows); I: Hematoxylin and eosin stained image (original magnification, × 200).
