Perianal abscess

Discussion:

An anorectal abscess arises from the epithelium of anal canal, from there infection can spread to intersphincteric space, ischiorectal fossa and supralevator space.

This is a case of an extensive perianal abscess with impending fistula formation and supralevator and intersphincteric extension with involvement of the left ischiorectal fossa.
