Ischiorectal abscess with retroperitoneal extension: masquerading as an appendicular abscess

The occurrence of a retroperitoneal abscess as an extension of ischiorectal abscess is exceedingly rare. It’s presentation may be late or atypical. Here, we present a case report of a 27-year-old male who developed an ischiorectal abscess with late symptoms of retroperitoneal spread. Retroperitoneal extension was diagnosed radiologically following complaints of right iliac fossa pain and loose motions. Early surgical management was performed successfully.
