ABSTRACT

Gastrointestinal duplications are uncommon congenital lesions that can occur anywhere along the alimentary tract, and the symptoms of which generally develop during infancy or childhood. Completely isolated duplication cysts are an extremely rare variant of duplication, where no communication between the cyst and the adjacent bowel segment is present. We report the unique case of an adult who presented with right lower abdominal pain and systemic signs of inflammation caused by infection of a completely isolated ileal duplication cyst. Histological examination of the cyst additionally revealed a low-grade mucinous cystadenoma. We discuss the clinical presentations, diagnosis and treatment of this rare entity.
