The pituitary gland is sometimes called the "master endocrine gland" because it makes hormones that affect the way many parts of the body work.

When blood from trauma irritates brain tissues, it causes swelling. This is known as cerebral edema. The pooled blood collects into a mass called a hematoma. These conditions increase pressure on nearby brain tissue, and that reduces vital blood flow and kills brain cells.
Bleeding can occur inside the brain, between the brain and the membranes that cover it, between the layers of the brain's covering or between the skull and the covering of the brain.
What Causes Bleeding in the Brain?
There are several risk factors and causes of brain hemorrhages. The most common include:
Head trauma. Injury is the most common cause of bleeding in the brain for those younger than age 50.
The symptoms of a brain hemorrhage can vary. They depend on the location of the bleeding, the severity of the bleeding, and the amount of tissue affected. Symptoms may develop suddenly or over time. They may progressively worsen or suddenly appear.
