About the Isabel Diagnosis Challenge

The New England Journal of Medicine (NEJM) publishes presentations of common diseases and unusual cases in the Clinical pathology Conference (CPC) series. The cases are educational and can pose diagnostic challenges even to the expert physicians.

Using the clinical features of these cases, evaluate your diagnostic skills and compare your performance to that of the physicians at MGH. If you are an Isabel client or have a free-trial subscription, use the diagnosis system to get a list of likely diagnoses.
