Fig. 8. Complex-type intersphincteric perianal fistulas in a 24-year-old female patient with perianal Crohn’s disease. (A) Axial T2-weighted magnetic resonance image (MRI) without fat saturation shows internal openings of two intersphincteric fistulas in the 11 o’clock and 2 o’clock directions (white arrows). (B) Coronal T2-weighted MRI without fat saturation shows the inferior extension of fistulas into the level of the lower rectum (white arrowheads). (C) Axial T2-weighted MRI without fat saturation shows the external opening of the left-sided fistula connected to the perineum (black arrow). (D) Axial diffusion-weighted image and (E) apparent diffusion coefficient map also show two fistulous tracts on both sides (black arrowheads).
