This case takes place in Minnesota and involves a 70-year-old patient who presented to the ER with dizziness and instability, after a period of exercise. She underwent an MRI and nothing showed up except some inflammation in the sinuses. The patient was diagnosed with a sinus infection and was started on treatment. She was admitted for monitoring. Approximately twelve hours later the patient’s condition had deteriorated such that a second MRI was performed which identified a diffuse subarachnoid hemorrhage. The patient underwent surgery to relieve the pressure. She was discharged home after five weeks in hospital and a rehab unit.
