Intussusception in the adult is unusual, and its etiology is mostly neoplastic. In most cases of intussusception, a polypoid tumor located in the terminal ileum invaginates within the cecum. We described an unusual case of adult intussusception associated with Salmonella typhimurium enterocolitis. Preoperative diagnosis of intussusception in the ileocecal region was made by ultrasonography, and the ileocecal region containing the mass in the cecum, causing the intussusception, was resected. Histological features of the mass included an edematous focal wall thickening. Later, the diagnosis of S. typhimurium enterocolitis was made by the preoperative stool cultures. This case demonstrated intussusception as a complication of S. typhimurium enterocolitis. It is worth noting that S. typhimurium enterocolitis is in fact a potential cause of intussusception.
成人肠套叠并不常见，其病因大多为肿瘤性。在大多数肠套叠病例中，位于回肠末端的息肉样肿瘤会套入盲肠内。我们描述了一例与鼠伤寒沙门氏菌肠炎相关的成人肠套叠罕见病例。通过超声对回盲部肠套叠进行了术前诊断，切除了包含盲肠内肿块并导致肠套叠的回盲部。肿块的组织学特征包括局灶性壁水肿增厚。后来，通过术前粪便培养确诊为鼠伤寒沙门氏菌肠炎。该病例表明肠套叠是鼠伤寒沙门氏菌肠炎的一种并发症。值得注意的是，鼠伤寒沙门氏菌肠炎实际上是肠套叠的一个潜在病因。
