Acromegaly with empty sella syndrome.

The commonest cause of acromegaly is due to GH hypersecretion from pituitary adenomas (95%). Acromegaly has rarely been found in patients with ES. It is important to exclude a past history suggestive of pituitary apoplexy. Extra-pituitary source of GH such as ectopic production of GHRH with resultant GH hypersecretion needs to be excluded. In such cases, since there is no resectable mass, medical therapy is the primary treatment option.
