Anorectal abscess

Common card · No. 337608

Anorectal abscess (also known as an anal/rectal abscess or perianal/perirectal abscess) is an abscess adjacent to the anus. Most cases of perianal abscesses are sporadic, though there are certain situations which elevate the risk for developing the disease, such as diabetes mellitus, Crohn's disease, chronic corticosteroid treatment and others. It arises as a complication of paraproctitis. Ischiorectal, inter- and intrasphincteric abscesses have been described.
