A 55-year-old man with a history of hypertension and migraines is sent by his primary care provider to the emergency department for a spinal tap to rule out meningitis. He states that he has had a headache for approximately 3 days that came on gradually and is in his midlower forehead and nose area bilaterally. He also feels neck stiffness and subjective fever but never checked his temperature. He denies any vomiting or photophobia. When asked, he says that the pain is slightly worse on the left side. He does not think that it is a migraine, because previous migraines had never lasted this long and he had never felt feverish from a migraine before. His sister happens to be with him and mentions that yesterday his left eyelid was quite droopy, but today it is less so.
Neurologic exam is normal. See image below of the patient’s eyes.
