Adult small intestinal duplication cyst presenting as a post appendicectomy abdominal mass

Gastrointestinal (GI) duplication cysts are rare congenital malformations. It may involve any level of the alimentary tract, but most commonly involves the ileum, oesophagus, and jejunum. Ileal duplication cysts represent approximately 4–8% of GI duplication cysts, the majority of which present in early childhood. We present a case of adult ileal duplication cyst in a 20-year old male found to have an abdominal mass. There are several potential methods to diagnose GI duplication cyst and treatment of choice is complete surgical resection. The Sri Lanka Journal of Surgery 2015; 33(3): 20-21
