Intraparenchymal Hematoma

Intraparenchymal hematoma

Intraparenchymal hematoma, also known as an intraparenchymal hematoma, is a form of hematoma that occurs when blood accumulates in the brain’s tissues. Trauma, rupture of a bulging blood vessel, poorly connected arteries and veins from birth, excessive blood pressure, and malignancies are all possible reasons. In addition, blood can flow into the brain as a result of diseases.

A blood clot within the skull is known as an intracranial hematoma. The rupture of a blood artery within the brain and trauma such as a vehicle accident or a fall are the most common causes. Blood can be drawn from within the brain tissue or beneath the skull, pressing against the brain.

Some head injuries are minimal, such as those that cause only a temporary loss of consciousness. An intracranial hematoma, on the other hand, can be fatal. It usually necessitates immediate medical attention, which may involve blood removal surgery.

The following are symptoms of a subdural hematoma:

The symptoms of an intracranial hematoma may arise immediately after a head injury, or they may take weeks or even months to show. After a brain injury, you may appear acceptable for a period known as the lucid interval. However, if pressure on your brain builds up over time, you may notice some or all of the following indications and symptoms:

  • Headache that is becoming worse
  • Vomiting
  • Drowsiness and a loss of consciousness that progresses
  • Dizziness
  • Disparities in pupil size
  • Speech slurred
  • Paralysis on the opposite side of the body as a result of the head injury

However, with time, pressure on your brain increases, producing some or all of the following signs and symptoms:

As more blood fills your brain or the narrow space between your brain and skull, other signs and symptoms may become apparent, such as:


Head injury, often from motor vehicle or bicycle accidents, falls, assaults, and sports injuries, is the most common cause of intracranial bleeding (hemorrhage).

If you’re an older adult — especially if you’re taking an anticoagulant or an antiplatelet drug, such as aspirin — even mild head trauma can cause a hematoma.

You can have a serious injury even if there’s no open wound, bruise or other obvious damage.

There are three categories of hematoma — subdural hematoma, epidural hematoma and intraparenchymal hematoma.
