Endoscopic ultrasonography (EUS) and magnetic resonance imaging (MRI) are becoming popular methods for examining tumorous lesions along the upper gastrointestinal tract. Though duplication cysts are uncommon, EUS findings from gastric duplication cysts have accumulated and proven very useful for preoperative diagnosis. There have been few reports, however, concerning MRI findings from these cysts. We report herein the case of a 25-year-old man with a gastric duplication cyst. EUS demonstrated a cystic mass adjacent to the fourth layer of the stomach wall. MRI revealed a cyst containing low signal-intensity fluid and high signal-intensity fluid separated by levels. In addition to the characteristic findings from preoperative examinations, the unique histological findings from the cyst are also described.
内镜超声检查（EUS）和磁共振成像（MRI）正成为检查上消化道肿瘤性病变的常用方法。虽然重复囊肿并不常见，但胃重复囊肿的EUS检查结果已积累起来，并被证明对术前诊断非常有用。然而，关于这些囊肿的MRI检查结果的报告却很少。我们在此报告一例25岁男性胃重复囊肿的病例。EUS显示胃壁第四层附近有一个囊性肿块。MRI显示一个囊肿，其中低信号强度液体和高信号强度液体分层分隔。除了术前检查的特征性发现外，还描述了囊肿独特的组织学发现。
