title: Biliary dilatation and duodenal intussusception secondary to enteric duplication cyst: MDCT diagnosis.
abstract: Enteric duplication cysts are rare congenital anomalies that may occur anywhere along the gastrointestinal tract, most commonly involving the small bowel. The distal ileum, jejunum, and duodenum are affected in descending order of frequency. We describe a case of biliary dilatation and duodenal intussusception caused by an enteric duplication cyst in an adult patient. To our knowledge, there are no other reported cases of this entity in an adult in the English literature. Multidetector computed tomography (MDCT) findings are emphasized, and the value of multiplanar reformation (MPR) in forming a correct preoperative differential diagnosis is discussed.
