A woman lost eyesight in one eye because a hospital failed to tell her about her brain tumor. This woman was involved in a car accident and suffered head trauma. She was taken to an emergency room where a CAT scan was done for her head. The doctor who evaluated the CAT scan correctly recognized an abnormal mass was growing in her brain-totally unrelated to her car accident and her recent trauma. The problem was that nobody told the patient about her growing brain tumor. This caused the tumor to grow and put pressure on the optic nerve, leading to blindness in one eye.
