Surgically proven gastro-gastric intussusception with malignant gastric GIST as the lead point. Axial contrast-enhanced CT reveals opacified blood vessels and mesenteric fat (white arrow) within intussusceptum (black arrow), which represents the lesser curvature of the stomach. The thin outline of the intussuscipiens is barely perceived (arrowheads). Inset: caudal axial section reveals a homogeneously enhancing mass as the lead point (arrowheads). Pathology revealed it to be a malignant GIST. True gastro-gastric intussusception is extremely rare and has been reported in polyps or in a gastric remnant through gastrojejunal anastomosis.
