Imaging appearance of malignancy associated gastrogastric intussusception in an elderly woman

A rare case of gastro‐gastric intussusception in familial adenomatous polyposis

“…Given its rarity, the diagnosis is frequently not considered. Prompt imaging is essential, with CT being the modality of choice 6 . Appearances of intestinal intussusception on CT have been described as a ‘target’ sign, where the bowel invaginating on itself creates duplicated layers of bowel wall forming concentric rings 1 .…”

“…Appearances of intestinal intussusception on CT have been described as a ‘target’ sign, where the bowel invaginating on itself creates duplicated layers of bowel wall forming concentric rings 1 . Imaging features of gastro‐gastric intussusception have not been reported but given it involves the same telescoping mechanism, similar appearances are expected 6 . Urgent surgery is required in adults as the intussusceptum can become ischaemic as oedema progresses.…”
