Guess Who's Coming to Dinner
Guess Who's Coming to Dinner is mostly a bottle episode, so the medical curation stays intentionally narrow: Maggie's UTI/STI testing and Callie's posterior shoulder dislocation consult are the only substantive patient-care threads.

Medical Cases in This Episode
These are the patient stories worth unpacking. Open any case for the real-world medicine, what the episode shows, what it leaves out, and source-backed context.
2 cases identified
Case 1
Maggie Pierce: UTI symptoms and STI testing request
Maggie's urinary frequency leads to UTI testing, STI concerns, and symptom-relief medication while results are pending.
- Episode shows
- Maggie has frequent urination during the dinner party, suspects a UTI, goes to the hospital for tests, asks for a full STI panel including HIV and hepatitis B, receives Pyridium and cranberry juice from Andrew, and waits for lab confirmation.
- Clinical takeaway
- The case separates symptom relief from diagnosis: urinary analgesics can help discomfort, but they do not confirm or cure infection.

Case 2
Callie's patient: posterior shoulder dislocation
Callie is pulled away from the dinner party because a posterior shoulder dislocation cannot be managed by phone guidance alone.
- Episode shows
- Callie is paged back to the hospital for a patient with posterior shoulder dislocation. She tries to talk the fellow through management over the phone, but the attempt fails and she goes in to check on the patient herself.
- Clinical takeaway
- The case is brief but clinically concrete: posterior shoulder dislocations are uncommon enough that escalation to an orthopedic surgeon is plausible.

Episode Summary
Guess Who's Coming to Dinner is dominated by the dinner-party fallout around Penny and Derek's death. The concrete medical material is limited to Maggie's urinary-symptom workup and Callie's on-call posterior shoulder dislocation case. Meredith's apple-slicing finger cut is documented in episode notes but is too minor for a public case card.
Differential Diagnosis and Testing Logic
Maggie's urinary frequency could fit UTI, but her request for STI testing is episode-supported and should not be mocked away as irrelevant. Callie's patient has a named posterior shoulder dislocation, but the episode does not provide mechanism, imaging, neurovascular status, or reduction outcome.
Medical Accuracy Review
The medical content is thin but mostly plausible. Maggie's use of Pyridium is best understood as symptom relief while testing is pending, not definitive infection treatment. Callie's shoulder consult is credible because posterior shoulder dislocations can be challenging and may need experienced reduction.
