The abdomen in this x-ray belonged to a mentally unstable man who swallowed a box-cutter blade. "Swallowing objects is very common in mental institutions," says Dr. Tim B. Hunter, professor of radiology at the University of Arizona and a collector of unusual X-ray images. But the blade passed without harm. Once they reach the large intestine, says Dr. Hunter, swallowed foreign bodies often pass without harm.
