What are intracerebral and scalp hematomas?

Intracerebral hematomas occur within the brain tissue itself. Intracerebral hematomas may be due to bleeding from uncontrolled high blood pressure, an aneurysm leak or rupture, trauma, tumor, or stroke.

Scalp hematomas occur on the outside of the skull and often can be felt as a bump on the head. Because the injury is to the skin and muscle layers outside of the skull, the scalp hematoma itself cannot press on the brain.

What are ear and nasal hematomas?

Ear hematomas may occur if an injury causes bleeding to the outside helix or cartilage structure of the ear. Often called boxer's ear, wrestler's ear, or cauliflower ear, blood gets trapped between the thin layer of skin and the cartilage itself. Since the ear cartilage gets its blood supply directly from the overlying skin, a hematoma can decrease blood flow causing parts of the cartilage to shrivel and die. This results in a bumpy, deformed outer ear called a "cauliflower ear."

Septal hematomas occur with nasal trauma. A septal hematoma may form associated with a broken nose. If not recognized and treated, the cartilage can break down and cause a perforation of the septum. Continue Reading
