Pituitary Gland - Hypophyseal Gland

.pdf Pituitary Clinical Implications

Hormones (Adenohypophysis)

• Growth Hormone
• Gonadotrophins
• Prolactin
• ACTH
• TSH

Neurohypophysis

• Arginine Vasopressin
• Oxytocin

Disease - Adenoma Hormone Hypersecretion

Functioning/Non-Functioning

Disease - Parasellar Lesions

Mass Effects: Neurological, Visual, Hypopituitarism

• Headaches, Hypothalamic damage, Brain damage
• 2-6 Cranial nerve damage
• CSF leak
• Damage to Optic chiasm → Visual field loss on lateral halves(Bilateral Hemianopia)
• Hypopituitarism - Defective secretion of hormones
