AB A  52-year-old  man  with  a  history  of  hypertension  and  a  30  pack-year  smoking  history  presents  to  the  emergency  department  following  the  sudden  onset  of  a  severe,  bilateral  headache.  He  denies  nausea,  vomiting,  and  head  trauma.  His  temperature  is  38°C,  heart  rate  is  110  bpm,  and  blood  pressure  is  162/91  mm  Hg.  He  is  alert  and  oriented  to  place  and  time.  His  left  pupil  is  dilated  and  nonreactive  to  light.  A  noncontrast  computed  tomographic  (CT)  scan  of  the  head  shows  diffuse  hyperdensity  within  the  subarachnoid  space.  A  CT  angiogram  is  performed  that  demonstrates  a  left  posterior  communicating  artery  aneurysm,  and  the  patient  undergoes  further  workup  with  digital  subtraction  angiography.
