Abstract：
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.
摘要：
肠重复囊肿（EDCs）是儿童罕见的先天性畸形，可以沿着胃肠道（GI）到处发展，回肠是最常见的定位。我们在此介绍了一例罕见的回肠起源的重复囊肿，该囊肿表现为管状形态，与胃肠道腔不连通。一个2个月大的男孩被送往我们医院，以调查右下腹的消声形成，以进行手术计划。患者无症状。超声（US）和磁共振成像（MRI）显示囊性病变的特征。进行腹腔镜手术并切除囊肿。宏观检查和组织学发现证实了回肠引起的肠重复囊肿的诊断。一个腹部囊性肿块的病人,虽然无症状，值得评估病变的性质并计划手术以避免未来的并发症。正确使用诊断是确定囊性肿块的病因和特征的基础。
