An ileal duplication cyst case report: From diagnosis to treatment

Enteric duplication cysts (EDCs) are rare congenital malformations of the children and can develop everywhere along the gastrointestinal (GI) tract, being the ileum the most frequent localization. We herein present an unusual case of duplication cyst of ileal origin who show a tubular morphology and doesn't communicate with GI lumen.A 2-month-old boy was admitted to our hospital for investigation of an anechoic formation of the lower right abdomen for the surgical planning. The patient was asymptomatic. Ultrasound (US) and magnetic resonance imaging (MRI) showed features of a cystic lesion. Laparoscopic surgery was performed and the cyst excised. Macroscopic examination and histologic findings confirmed the diagnosis of a enteric duplication cyst arising from the ileum.In a patient with an abdominal cystic mass, although asymptomatic, it's worth assessing the nature of the lesion and planning a surgery in order to avoid future complications. A correct use of diagnostic it's fundamental to identify the etiology and the characteristics of a cystic mass.
