Clinics in diagnostic imaging (204). Gastro-gastric intussusception due to gastric gastrointestinal stromal tumour (GIST).

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.
