Congenital cystic duplications of the alimentary tract are rare, but can occur anywhere along the GI tract. Ileal duplication cysts account for the majority of diagnosed cases. Symptoms generally develop during infancy or childhood, with diverse presentations. Common manifestations include abdominal pain, an abdominal mass, vomiting, occasional intussusception, perforation, bleeding, and obstructive symptoms. In this report, we present the case of a 20-year-old man with an ileal duplication cyst with obscure lower gastrointestinal bleeding. The patient underwent cyst excision with a primary end to end anastomosis. The patient was discharged on the postoperative 7th day without any complications.
