SPR Unknown Case Contest

Welcome to the unknown case contest page!

The current unknown case is at the top; the previous cases are shown below with their answers.

We display the current unknown case for approximately two weeks, and accept answers during that time period. Please submit only one answer per case.

At the end of the year, the individual with the most correct answers will be honored with a prize (trainees will be judged separately from attendings).

If you would like to submit an unknown case for consideration to be displayed in the future, please go to this online form and follow the instructions.
