Description

Pituitary size can be accurately determined by using MRI and should be correlated with the patient's age and sex for further correlation. Pituitary gland size increased during puberty and it completely fills the pituitary Iossa. Decline in gland size with age reflect the endocrinology of aging and physiological atrophy. In the cases where there is a borderline abnormality in the size and shape of pituitary gland, it should be further evaluated by dynamic contrast study on MRI.
