Acromegaly is the clinical syndrome that results from excessive secretion of growth hormone (GH). The most common cause of acromegaly is a somatotroph (GH-secreting) adenoma of the anterior pituitary gland. In rare cases, overproduction of GH-releasing hormone (GHRH) by functional hypothalamic tumors such as hamartomas and gangliocytomas may cause acromegaly by inducing proliferation of GH-secreting pituitary cells.1 However, to our knowledge, few cases of combined pituitary adenoma and sellar gangliocytoma presenting with acromegaly have been reported.2
