Bay Area News reported a story about a teen girl who outsmarted her doctors by correctly diagnosing herself with Crohn’s disease, after her doctors missed it and said that she had irritable bowel syndrome.

Apparently she was taking a Biomedical Problems class and pathologists came to the class to teach the students how to correctly diagnose slides. Later she took slides of her own intestinal tissue to the class. Looking at one of the slides, she thought she found something and called over her teacher. The teacher snapped a picture of the slide and sent it to a pathologist. The pathologist confirmed that it was a granuloma.
