Doctor's Notes on Hematoma

A hematoma is a collection of blood outside of a blood vessel. Hematomas can occur anywhere in the body and are often described by their location, such as subdural hematoma, epidural hematoma, intra-abdominal hematoma, or hepatic hematoma. Hematomas can be caused by bleeding due to any cause including trauma or injury, defects in blood vessels, or problems with blood clotting.

Symptoms and signs of hematomas may include a bluish discoloration of the skin or lump beneath the skin. When the hematoma is present inside the skull cavity, associated symptoms and signs can include headache, confusion, seizures, loss of bladder or bowel control, or other neurologic symptoms. Signs and symptoms of a hematoma are very specific to the exact location within the body.
