Clinical Reasoning: A 21-year-old woman with right eye swelling and bruising

A 21-year-old woman presented with right eye swelling and bruising. Several weeks prior to admission, she had bifrontal headaches associated with a "whooshing" pulsation in her right ear. She went to a local emergency department where CT scan of the brain was read as negative. One week later, she noticed that her right eye was turned toward her nose. She denied diplopia. On the day of admission, she awoke and noticed bruising under her right eye accompanied by swelling. She also had blurry vision.
