Young woman presents with painful ophthalmoplegia in left eye

A 20-year-old woman presented to Tufts New England Eye Center with 1 day of progressively worsening left eyelid swelling and pain with eye movement. Symptoms initially began 10 days before presentation with purulent nasal discharge, which was diagnosed by an outside hospital as viral sinusitis and treated with a short course of oral methylprednisolone and fluticasone nasal spray. Three days later, she developed tooth pain and dysphagia, followed by severe headaches, for which she returned to the emergency room. She was diagnosed with migraine headache exacerbation and discharged on a “migraine cocktail” consisting of sumatriptan, aspirin/acetaminophen/butalbital and verapamil. Her migraine symptoms never fully resolved, and she began to feel increasingly lethargic. The day before presentation, she developed fever, neck pain and left eye pain. Her left eye pain was worse with movement and associated with redness, photophobia and blurred vision. She also reported intermittent diplopia and inability to close the left eye fully.
