It has been reported that ingested magnets can cause intestinal fistula formation or perforation, leading to intestinal obstruction. However, there are no previous case reports that magnet ingestion additionally caused an intestinal volvulus. We report herein the case of a 1-year-old boy in whom the ingested magnets caused a volvulus of part of the small intestine leading to the resection of the necrotic portion. We think that if more than one magnet is found as a foreign body in the intestine, they should be removed immediately by laparotomy. Clinicians who care for children should be aware of this unexpected risk.
