The case of a girl who swallowed 18 magnetic balls

They can pull the intestines together affecting blood flow, leading to necrosis, gangrene and perforation, doctors warn

The case of a four-year girl who swallowed 18 magnetic balls is a timely reminder to consider foreign body ingestion when otherwise healthy kids present with colicky abdominal pain, her treating doctors say.

The girl presented with a 10-day history of vomiting and abdominal and pain, and more recently constipation, which had been diagnosed as acute gastroenteritis and gastritis at other hospitals.
