Cryptoglandular abscess results from infection of the anal glands in the crypts at the dentate line. The initial abscess occurs in the intersphincteric space. Infection then can spread (1) superficial to the external sphincter into the perianal space, (2) through the external sphincter into the ischiorectal space (which in turn may connect posteriorly via the deep postanal space, resulting in a horseshoe abscess), or (3) deep to the external sphincter into the supralevator space.
