Core Tip

Core tip: Duodenal duplication cysts are rare congenital anomalies that have been seldom reported in adults. Most cases of duodenal duplication have been associated with pancreatitis or jaundice and few have been reported as a cause of gastrointestinal hemorrhage. We submit a case of duodenal duplication cyst causing gastrointestinal hemorrhage. In rare cases, duodenal duplication cysts may cause gastrointestinal bleeding and must be included in the differential diagnosis.
