Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings. Increased awareness of these atypical imaging features can lead to early diagnosis and decrease the risk of potential complications including mesenteric venous thrombosis, bowel ischemia and necrosis.
小儿小肠套叠（SBI）在大多数情况下可自发缓解。小儿病理性小肠套叠伴引导点较为罕见。超声（US）是诊断肠套叠的首选初始影像学检查方法。我们报告一例由巨大错构瘤性息肉引起的长段SBI及继发性肠梗阻病例。该病例强调了小肠套叠可能出现的独特、非典型超声表现，并与相关的放射学、CT（计算机断层扫描）及术中表现相关。提高对这些非典型影像学特征的认识可实现早期诊断，并降低包括肠系膜静脉血栓形成、肠缺血和坏死在内的潜在并发症风险。
