11C-methionine PET can aid localisation of the source of ACTH-dependent Cushing’s syndrome in patients with equivocal or negative conventional imaging.

Background: Cross-sectional imaging (e.g. CT/MRI) can not always reliably identify the site of ACTH secretion in Cushing’s disease (CD) or the ectopic ACTH syndrome (EAS). We report our experience of localising the source of ACTH-dependent Cushing’s syndrome, using functional imaging with 11C-methionine positron emission tomography (Met-PET).Methods: Forty consecutive patients with: (i) de novo ...

Bilateral Inferior Petrosal Sinus Sampling (BIPSS) reliably differentiates pituitary from ectopic Cushing’s syndrome, but does not predict pituitary tumour location, especially when lateralizing to the right

White Louisa , Tobin Jake , Koulouri Olympia , Powlson Andrew , Bashari Waiel , Koo Brendan , Gurnell Mark

Background: BIPSS is considered the gold-standard procedure for differentiating autonomous pituitary [Cushing’s Disease (CD)] and ectopic ACTH syndrome (EAS) sources of ACTH hypersecretion. A basal (i.e. unstimulated) pituitary:peripheral ACTH ratio >2, and/or a CRH stimulated pituitary:peripheral ACTH ratio >3, have been proposed as indicative of CD, with a range of sensitivities and specificities cited in the literature. Ad...
