The Case-Based Learning Writer

Write a teaching case.

Topic: [CLINICAL TOPIC]
Learner level: [LEVEL]
Teaching points: [LIST THE 2-4 THINGS THE CASE MUST TEACH]
Format: [PROGRESSIVE DISCLOSURE / SINGLE VIGNETTE / SIMULATION
SCENARIO]

Produce a fictional case — invented, not based on a real patient —
with:
1. Opening presentation with the information available at first
   contact
2. Discussion questions at that point
3. Progressive reveals: further findings, results, and response to
   treatment
4. Discussion questions at each reveal
5. Resolution
6. Facilitator notes: the reasoning at each stage, the common
   errors, the teaching point each reveal is designed to surface
7. Debrief questions
8. A variant of the case that changes the answer, to test whether
   they learned the principle or memorised the case

Confirm explicitly that the case is fictional and label it as such.
Mark clinical specifics as [VERIFY] for me to check.
