What is a hematoma?

A hematoma refers specifically to an accumulation of blood outside of blood vessels, typically resulting from a break or leak in a blood vessel. This accumulation can occur in various parts of the body, including the brain, where it is particularly concerning. In the context of brain injuries, a hematoma can lead to increased pressure on the brain, which may cause significant neurological complications. The pressure from the collected blood can compress brain tissues, leading to symptoms such as headache, confusion, or loss of consciousness, depending on its size and location.

Understanding a hematoma as an accumulation of blood emphasizes the importance of timely medical intervention to manage the pressure it creates. Without proper treatment, the increased intracranial pressure can result in serious outcomes, such as brain damage or death. Therefore, recognizing and diagnosing a hematoma is critical in the management of brain injuries.
