What is an intramural hematoma?
Aortic intramural hematoma (IMH) is a condition characterized by blood leaking through the innermost layer of the aortic wall and flowing between the inner and outer walls. This leakage does not occur due to a tear in the aortic wall and, because of this, the condition has been difficult to diagnose until recently.

What causes a subdural hematoma in the brain?
Subdural hematoma: A subdural hematoma occurs between the brain tissue and the internal lining of the brain. Injuries and trauma are the most common causes of hematomas. Any damage to the walls of the blood vessels may cause blood leakage. This blood pools as it escapes the blood vessel, causing a hematoma.
What is the difference between a bruise and a hematoma?
A bruise develops when blood leaks from smaller blood vessels, causing a purple, blue, or darkened spot to appear on the skin.
