Good Eyes
Jessica Terry, 18, discovered a granuloma while looking at her own intestinal tissue slides in an Advanced Placement science class in her high school, ending the mystery about her previously un-diagnosed illness.
CNN Senior Medical Correspondent Elizabeth Cohen reports how physicians were puzzled by Terry's symptoms, until she spotted the granuloma, which was confirmed after her teacher sent a digital photo taken at the microscope to her pathologist, who then diagnosed the teenager with Crohn's disease.
The article mentions how some diseases are difficult to diagnose, and recommends some samples get a second review. While Terry's eyes might have made a valuable addition to the lab, she is entering nursing school in the fall.
