A 45 year old woman presents complaining of weakness that comes and goes. It's worse in the evening and after she plays tennis. She also complains that her tennis game is being affected because sometimes things "look funny." You suspect she's seeing double. On exam, you notice ptosis.
CXRs are shown above. You recognize the abnormality and remember the differential with the "T mnemonic."
Challenge: What's your diagnosis?
1. What's the finding on the CXRs?
2. What's the T mnemonic? (or what is the differential for the abnormality?)
3. How does that relate to the patient's presentation?
