Befuddling Pupillary Asymmetry
A medical student on your team asks you to review an 81 year-old female who speaks little English. She was BIBA to the ED following a fall. Her nursing home transfer sheet says that the fall was witnessed: she tripped and there was no loss of consciousness. The student is concerned that the patient’s right pupil is fixed and slightly dilated in the presence of facial abrasions. Facial views have been ordered.
