A pituitary macroadenoma is a benign (non-cancerous) growth in the pituitary gland that is larger than 10 millimeters in size. A pituitary macroadenoma differs from a pituitary microadenoma, which is smaller than 10 millimeters. Understanding the Pituitary Gland.
The pituitary is a pea-sized gland that is housed within a bony structure (sella turcica) at the base of the brain. The sella turcica protects the pituitary but allows very little room for expansion. The pituitary controls the function of most other endocrine glands and is therefore sometimes called the master gland. In turn, the pituitary is controlled in large part by the hypothalamus, a region of the brain that lies just above the pituitary.
