The Case Challenge series includes difficult-to-diagnose conditions, some of which are not frequently encountered by most clinicians but are nonetheless important to accurately recognize. Test your diagnostic and treatment skills using the following patient scenario and corresponding questions. If you have a case that you would like to suggest for a future Case Challenge, please contact us.


A 52-year-old African-American man is brought to the emergency department by his family for evaluation of headache, nausea, blurry vision, and confusion. The patient is somnolent but arousable and oriented to person only.

His medical history is significant for morbid obesity, hypertension, hyperlipidemia, and prediabetes. His medications include nifedipine, chlorthalidone, and atorvastatin. His family history is notable for hypertension, peripheral vascular disease, transient ischemic attack (father), and diabetes (mother).
