Abstract

We present the clinical, laboratory, computed tomography (CT), single photon emission computed tomography (SPECT), and histopathological findings of a patient with adrenocorticotropic hormone (ACTH) dependent Cushing's syndrome with massive bilateral adrenal gland hyperplasia due to a hilar ACTH-producing well-differentiated neuroendocrine carcinoma.

Keywords: 111In-pentetreotide (Octreoscan); Bilateral adrenal gland hyperplasia; Cushing’s syndrome.
