Diagnosis and treatment of acromegaly

Acromegaly is a clinical syndrome that most typically is the manifestation of adenomatous hyperplasia of growth hormone-secreting cells in the pituitary gland. Although the primary process is benign, many disfiguring and potentially serious complications can develop. Because of the slow evolution of signs and symptoms, acromegaly can be a diagnostic challenge. Furthermore, many common diseases, such as hypertension, diabetes mellitus and hyperlipidemia, occur secondary to acromegaly but may initially be treated as isolated primary processes. Systematic evaluation should be performed if acromegaly is suspected. The diagnosis is based on clinical observation, hormonal assays and selective radiologic imaging. Acromegaly is most often treated surgically, but radiotherapy and drug therapy can be effective alternatives.
