Hypopituitarism occurrs secondarly to ischemia of the pituitary gland. This ischemia can be due to hemorrhage, tumors, or brain injury. Compression of the blood vessels is one of the mechanisms that cause ischemia to the pituitary gland and leads to hypopituitarism. Pituitary adenomas cause compression of the hypophyseal vessels leading to interruption in the blood supply of the pituitary gland. Traumatic brain injury either primary or secondary also leads to pituitary gland dysfunction.
