A hematoma is a collection of blood outside of a blood vessel.
There are several types of hematomas and they are often described based on their location.
A scalp hematoma is a collection of blood (either flowing or clotted) from ruptured blood vessels that will then collect in the area of space and tissue between the skull and skin. Although the hematoma and bruising are on the outside of the brain and cannot create any pressure or problems in the skull, it is still a strong indication that there has been some head trauma that needs to be investigated and treated.
If a scalp hematoma is caused by head trauma and the person is not exhibiting any symptoms, then it is still advisable for the individual to seek medical attention. The brain may still have suffered damage without any problems manifesting straight away. The individual will be tested through a variety of neurological exams, and may also undergo scanning procedures in order to rule out internal bleeding.
On the other hand, if a person has experienced head trauma and is exhibiting even one of the symptoms listed below, then they should be checked out by an emergency physician immediately. It is possible that there is bleeding in the brain or another type of trauma that may require immediate medical attention. Brain trauma is a very serious condition, and without the right treatment the patient can experience long-term problems or even die from their complications.
