    1. Patient presentation

    • An 89-year-old man presents to the emergency room in a comatose state. He was
      found in bed by his relatives about one hour prior to presentation; the exact duration of his loss
      of consciousness is unknown. No epileptic seizures have been observed and medication intake was
      denied. The past medical history is largely unremarkable.
    • An unenhanced CT of the brain is unremarkable.
    • Directly after the unenhanced CT, a CT-angiography is performed.
