A 10-month-old German Shepherd Dog presented for evaluation of intermittent vomiting. Abdominal radiographs revealed a marked right cranial mass effect. Initial differentials included abscess/cyst or less likely neoplasia from undetermined origin. On abdominal ultrasound the mass appeared cystic and thin walled. Computed tomography revealed a large cystic lesion originating from the pyloroduodenal junction causing pyloric outflow obstruction. A noncommunicating duodenal duplication cyst was found on exploratory laparotomy and further confirmed with histopathology and immunohistochemistry. Enteric duplication cyst should be considered as a differential in young dogs with gastrointestinal signs and a cystic abdominal mass detected with different imaging modalities.
一只10个月大的德国牧羊犬因间歇性呕吐前来评估。腹部X光片显示右颅侧有明显的占位效应。初步鉴别诊断包括脓肿/囊肿，不太可能是来源不明的肿瘤。腹部超声检查显示该肿块呈囊性且壁薄。计算机断层扫描显示一个起源于幽门十二指肠交界处的大囊性病变，导致幽门流出道梗阻。在剖腹探查术中发现了一个非交通性十二指肠重复囊肿，并通过组织病理学和免疫组织化学进一步证实。对于有胃肠道症状且通过不同成像方式检测到腹部囊性肿块的幼犬，应考虑肠道重复囊肿作为鉴别诊断。
