Horseshoe perianal abscess

Discussion:

Horseshoe perianal abscess occurring 2 weeks after a hard fall onto the buttock region. Perianal abscesses most commonly occur due to infected anal glands at the dentate line (mucocutaneous junction). However, given the history of a fall, trauma may have resulted in a mucosal injury or anal gland obstruction, leading to the abscess formation. 

The abscess is outside of the external anal sphincter and localized in the ischiorectal fossa. Treatment is incision and drainage.
