Signet ring cell carcinoma (SRCC) is an uncommon and poorly differentiated tumor. It arises mostly in the gastrointestinal tract. The incidence of gastric SRCC has increased in the past few years. Volvulus is the twisting of the bowel around its mesentery. It is classified as either primary or secondary. It is relatively common in the cecum and sigmoid colon. Volvulus of other parts of the gastrointestinal tract is relatively rare. Herein, we present a case of small bowel volvulus (SBV) secondary to advanced gastric SRCC with peritoneal carcinomatosis. The patient had presented with nausea and vomiting. Initial computed tomography (CT) scan of abdomen unveiled jejunal volvulus. SBV resolved spontaneously on a repeat CT scan. Enteroscopy with histopathology confirmed the diagnosis of gastric SRCC, which turned to be metastatic to peritoneum on laparoscopy. We believe our case is unique due to the rarity of advanced gastric SRCC presenting as secondary jejunal SBV without appreciated gastric mass on imaging.
印戒细胞癌（SRCC）是一种罕见且分化程度低的肿瘤。它主要发生在胃肠道。在过去几年中，胃SRCC的发病率有所上升。肠扭转是指肠管围绕其系膜扭转。它分为原发性或继发性。在盲肠和乙状结肠中相对常见。胃肠道其他部位的肠扭转相对少见。在此，我们报告一例继发于晚期胃SRCC伴腹膜转移癌的小肠扭转（SBV）病例。患者表现为恶心和呕吐。腹部初次计算机断层扫描（CT）显示空肠扭转。重复CT扫描时SBV自行缓解。经肠镜检查及组织病理学检查确诊为胃SRCC，腹腔镜检查显示已转移至腹膜。我们认为我们的病例很独特，因为晚期胃SRCC表现为继发性空肠SBV且影像学上未发现胃部肿块的情况很罕见。
