Clinical presentation
Patients have presented with anorectal bleeding and/or pain.

The few cases have either not been characterized on imaging or only imaged on barium studies.
Differential diagnosis
Differential diagnosis is limited, but the more common perianal fistula and/or abscess needs to be considered.
