A relatively thick-walled fistulous track traverses both internal and external anal sphincters piercing and penetrating through the left ischioanal fossa. Its internal opening pierces the anal canal anteriorly near 1 o’clock where a fairly defined restricted collection / abscess formation is seen. The collection measures 1.8 x 1.5 cm. It shows restricted diffusion. Then the thick track protrudes and proceeds to make a hook down anteriorly along the ischioanal fossa for a length of about 9.7 cm. Its external opening being near 3 o'clock. The track has a thick enhanced wall and high signal intensity enhanced content.
