Abstract
One-third of patients affected by chronic inflammatory bowel diseases (IBDs) also suffer from fistulas of different sizes and types. The majority of fistulous tracts are identified in the anal rectal area, with chronic inflammation, and in the surrounding perivisceral adipose tissues [1]. Diagnostic imaging aims to identify and depict the complex fistulous tracts that can appear at the top of the anal canal as well as the potential involvement of the anal sphincter and the extension of the fistula to the ischioanal fossa.
