Overview
Pathophysiology
Background on pituitary gland blood supply
- In order to understand the pathophysiology of hypopituitarism, it is necessary to know the blood supply of the pituitary as the disease occurs mainly by ischemia through different mechanisms like hemorrhage, tumors or brain injury.[1][2]
- Pituitary gland is composed of two parts anterior (adenohypophysis) and posterior (neurohypophysis). Both parts are supplied by the carotid arteries.
- Adenohypophysis: It receives blood supply from the long and short hypophyseal arteries which arise from the internal carotid artery and the anterior of circle of willis.
- Neurohypophysis: It receives the blood supply from the inferior and middle hypophyseal arteries.
Pathogenesis
- Hypopituitarism pathogenesis is mainly due to destruction of the gland cells by different ways like ischemia, inflammation or infiltration.[3]
