A woman in her late 40's visited an emergency room with complaints of dizziness and headaches. The hospital performed various diagnostic tests on her but failed to find the cause of her symptoms on this visit, so she was discharged. Her symptoms persisted after her discharge from the hospital, and after she returned to the emergency room four days later, the hospital discovered that she had been suffering a leaking brain aneurysm for the past four days. She was transferred to a different hospital where her aneurysm was surgically repaired. However, the aneurysm left her with permanent speech and cognitive impairments. Had the hospital timely discovered the aneurysm four days earlier, she would have likely recovered with no permanent brain damage. The hospital was sued for failing to discover her aneurysm four days earlier.
