She lived for 99 years with organs in all the wrong places and never knew it

The reason? A condition called situs inversus with levocardia, in which most vital organs are reversed — almost like a mirror inside the body. That, along with a host of other weird but wonderful abnormalities, made Bentley a sort of medical unicorn. “I think the odds of finding another person like her may be as remote as one in 50 million,” said assistant professor Cameron Walker, who teaches the Foundations of Clinical Anatomy class at Oregon Health and …
