The Isabel tool touts an extensive database of conditions, and we often will test its accuracy with New England Journal of Medicine cases.
The New England Journal of Medicine (NEJM) publishes interesting presentations of common diseases and unusual cases in the Clinical pathology Conference (CPC) series. These cases are educational and can pose diagnostic challenges even to the expert physicians at the Massachusetts General Hospital.
Access the full case here (if you are a NEJM subscriber).
