Old people get hematoma's easy, their thin skin shows it more, plus being on a blood thinner, one is more susceptible to getting these hematoma's. So why is he taking a blood thinner? The first thing that comes to my mind is stroke prevention, or had a previous stroke and prevents it from becomng worse. Could be he has a vessel blockage in his brain and the thinners let the blood flow.
