Combining 11C-metomidate PET/CT and 18F-FDG PET/CT – a new approach to phenotyping indeterminate adrenal lesions

Senanayake Russell , Bashari Waiel , Bisambar Chad , Mendichovszky Iosif , Cheow Heok , Kosmoliaptsis Vasilis , Casey Ruth , Gurnell Mark

Background: 11C-Metomidate (MTO)-PET/CT has recently found utility as an alternative to adrenal vein sampling for lateralisation in primary aldosteronism. MTO binds with high affinity to 11b-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) and can be considered an adrenocortical-specific tracer. We and others have therefore hypothesised that combining MTO-PET/CT with 18F-FDG(FDG)-PET/CT would permit indeterminate adrenal lesions ...

Adenoma to carcinoma progression of a deoxycortisol-secreting adrenal cortical carcinoma in a 71 year old man presenting with hypokalaemia

Talbot Fleur , Powlson Andrew , Marker Alison , Gurnell Mark , Kosmoliaptsis Vasilis , Challis Ben , Casey Ruth

Case history: We present a 71 year old man, with a 3 year history of problematic hypertension (BP exceeding 190/100 on treatment), incidentally found to be hypokalaemic (K 1.8 mmol/l) during investigations for leg weakness. He had no clinical features to suggest an endocrinopathy. Investigations at his local centre revealed hypokalaemia dating back over 3 years.Investigations: Biochemistry:Na 142 mmol/l (135–145 mmol/l)<p ...

The primary aldosteronism rollercoaster: hypoaldosteronism as a potential postoperative complication

Palma August , Hu Lihua , Cheow Heok , Mendichovszky Iosif , Kosmoliaptsis Vasilis , Marker Alison , Bashari Waiel , Senanayake Russell , Gurnell Mark

Introduction: Primary aldosteronism (PA) is a common and potentially reversible cause of secondary hypertension, characterised by resistance to standard antihypertensive therapy and possible hypokalaemia. Lateralisation investigations, including adrenal vein sampling (AVS), are required to distinguish between unilateral or bilateral disease, with unilateral disease representing a potentially surgically curable form of PA. The majority of patients proceeding to adrenalectomy re...

[11C]Metomidate PET/CT can aid decision-making in patients with primary aldosteronism

Background: Primary aldosteronism (PA) is the leading, potentially reversible, cause of secondary hypertension. For most patients in whom surgery is being considered, adrenal vein sampling (AVS) is recommended to distinguish unilateral and bilateral causes. However, AVS remains technically challenging, and a significant proportion of patients are unable to progress to surgery because AVS is unavailable or unsuccessful. We have explored whether [11C]Metomidate PET/CT...

Introduction: In a prospective within-patient study (MATCH) 11C-metomidate PET-CT (MTO) was an accurate non-invasive alternative to adrenal vein sampling in the detection of unilateral PA1. Post-adrenalectomy (ADX), 24/78 (30%) patients achieved complete clinical success (PASO consensus) at 6 months, but 75% achieved reduction in B-type natriuretic peptide (BNP).Aim: To determine: 1. the number of patients who sustain complete clinical success...
