    1. Patient presentation

    • A 62-year-old man suffered an abrupt reduction of consciousness. When he arrived at the
      emergency room, he was comatose.

    • The patient’s medical history was unremarkable.
    • Laboratory tests were normal, although electrocardiography revealed atrial fibrillation.
    • Non-enhanced MDCT of the neurocranium was performed to rule out a neurovascular insult.
