Yes you can file a lawsuit against the Michigan hospital for misdiagnosis of a subarachnoid hemorrhage. Physicians are trained to suspect an subarachnoid hemorrhage when the patient presents to them with the signs and symptoms of the condition. Timely diagnosis is important to prevent permanent damage. If diagnosed in a timely manner, significant damage and injury can be avoided with proper surgical treatment. However, if a doctor or hospital misdiagnosis the condition, serious injury and harm to the patient may result. Therefore, when a doctor or hospital fails to diagnose a subarachnoid hemorrhage, and due to that misdiagnosis, you suffer serious injury, it can give rise to the filing of a medical malpractice lawsuit.
