A 95-year-old woman presented with abdominal bloating and anorexia of one week's duration. Contrast-enhanced computed tomography (CT) revealed features in keeping with gastro-gastric intussusception with a lead mass. Oesophagogastroduodenoscopy demonstrated a large 5-cm pedunculated fundal mass intussuscepted into the distal stomach. The patient subsequently underwent endoscopic polypectomy and open gastrostomy. Histological evaluation of the gastric mass revealed a gastrointestinal stromal tumour. Her postoperative course was uneventful. We herein describe the radiological features of adult intussusception and illustrate the usefulness of CT in the detection and characterisation of lead masses.
一位 95 岁女性因腹胀和食欲不振一周就诊。增强 CT 显示符合胃-胃内套叠特征，伴有铅块样肿块。上消化道内镜检查显示 5cm 大小的带蒂胃底肿块套叠入远端胃。患者随后接受内镜息肉切除术和开放式胃造口术。胃肿块的组织学评估显示胃肠道间质瘤。患者术后情况良好。本文描述了成人肠套叠的影像学特征，并说明了 CT 在检测和特征描述铅块样肿块方面的作用。
