What you need

To build a case study, you should assemble the following:

1. information about the patient's clinical history and relevant physical examination findings
2. a list of plausible differential diagnoses
3. a list of investigations that yielded abnormal results, with all of the relevant test data and images
4. optionally, if full results are available for the patient, a list of all other investigative findings
5. a list of investigations that will be nominated as likely to have been ordered by an expert
6. information about the diagnostic strategy that is appropriate in such cases
7. other relevant information e.g. relating to prognosis or management.
