Coronal contrast-enhanced MR image shows the fistula with contrast enhancement
Axial contrast-enhanced MR image shows the fistula and inflammatory tissue within the left intersphincteric plane.
Coronal T2SE MR image shows a fistula (arrow) within the left inter-sphincteric plane. Note the entry site in midline in the lower third of the anal canal.
Axial T2SE MR image shows the fistula (arrow) as a dot.
Axial T2SE MR image higher shows the fistula approaching the midline at 12 hour which is unusual.
