A 52-year-old woman presents to the emergency department with sudden-onset, severe occipital headache that began 1 hour ago while lifting a heavy box. She calls it the worst headache of her life and has nausea and brief neck stiffness. She has no fever, photophobia, or history of head trauma. Neurologic examination shows no focal deficits. Noncontrast CT head shows hyperdensity in the basal cisterns compatible with subarachnoid hemorrhage from a saccular aneurysm at a circle of Willis branch point.
