Primary tumors of the esophagus are extremely rare in children. A common periesophageal mass in children is duplication. It constitutes only 0.5 to 2.5% of all esophageal lesions usually diagnosed in infancy or early childhood. Duplication of the esophagus may be diagnosed on examination by the emergency department (ED) physician when it produces symptoms or when it is inadvertently found on a chest radiograph. The duplication may produce acute gastrointestinal symptoms such as vomiting and dysphagia or respiratory symptoms such as cough, wheezing, or dyspnea. Currently the examination of choice for evaluation of esophageal duplication is a barium swallow. However, computed tomography (CT) has the advantage over conventional diagnostic procedures, since it demonstrates the cystic nature of the mass and its relationship to adjacent structures in a noninvasive manner. An esophageal duplication has a well-marginated spherical mass contiguous with the esophagus, with preserved surrounding fat planes, and numbers of 15 to 30 Hausenfield units (HU) on CT. We are reporting three cases of this anomaly as demonstrated by CT.
食管原发性肿瘤在儿童中极为罕见。儿童常见的食管周围肿块是食管重复畸形。它仅占通常在婴儿期或幼儿期诊断出的所有食管病变的0.5%至2.5%。当食管重复畸形产生症状或在胸部X线片上无意中被发现时，急诊科医生在检查时可能会做出诊断。这种重复畸形可能会产生急性胃肠道症状，如呕吐和吞咽困难，或呼吸道症状，如咳嗽、喘息或呼吸困难。目前，评估食管重复畸形的首选检查是吞钡检查。然而，计算机断层扫描（CT）比传统诊断方法具有优势，因为它能以非侵入性方式显示肿块的囊性性质及其与相邻结构的关系。食管重复畸形在CT上表现为与食管相邻的边界清晰的球形肿块，周围脂肪平面保存完好，密度为15至30豪斯菲尔德单位（HU）。我们报告3例经CT证实的这种异常病例。
