 This is a 24-year-old man who was seen here originally on the 13th with a headache and found to have a mass on CT scan.  He was discharged home with a follow up to neurosurgery on the 14th.  Apparently, an MRI the next day showed that the mass was an aneurysm and he is currently scheduled for an angiogram in preparation for surgery.  He has had headaches since the 13th and complains now of some worsening of his pain.  He denies photophobia, fever, vomiting, and weakness of the arms or legs.
