  The format should be as follows: The format should be as follows: Case summary (based on video vignette); Usual presentation (symptoms, manifestations, and clinical signs); Why was the diagnosis missed? (e.g. unusual presentation, lack of proper testing, lack of basic science knowledge) Laboratory evaluation (blood work and imaging); Treatment (e.g. medication and surgery); Background (historical perspective and epidemiology); Conclusion (summarize major points, what did you learn?)

3.  Oral Presentation
