Background: Adrenal incidentaloma (AI) increasingly pose a diagnostic challenge. This retrospective observational study evaluated biochemical investigations performed in patients referred to Endocrine Surgery with AI and assessed adherence to Guidelines. Biochemical, histological and radiological characteristics of AI were also reviewed.Methods: Data were collected from Hospital and Laboratory records for referrals between January 2012–April 2014.</...

Backgound: We report a case of a 63-year-old postmenopausal female diagnosed with ovarian hyperthecosis masked by concurrent use of an aromatase inhibitor.Following diagnosis of breast cancer in 2009, requiring mastectomy with adjunctive chemotherapy, she was commenced on anastrozole. Later she noted gradual onset of frontal balding and hirsutism. Biochemistry revealed elevated serum levels of testosterone 13.2 nmol/l (range: <1.9 nmol/l) and androst...

Introduction: Clinical Practice Guidelines1 advocate adrenal vein sampling (AVS) to distinguish between unilateral and bilateral primary aldosteronism (PA). Cannulating the right adrenal vein is difficult, and there is a lack of standardisation in sampling procedure and interpretation2. We audited our local service to identify improvements.Methods: All AVS procedures performed between January 2018-December 2020 (n = 31) wer...

A 26-year-old Caucasian female presented at 14 weeks gestation with a 6-week history of lethargy, nausea and vomiting during her first pregnancy. Her adjusted Calcium was 4.12 mmol/l and parathyroid hormone (PTH) 26 pmol/l, consistent with possible primary hyperparathyroidism. She was previously well apart from occasional migraines. There was no known history of familial hypercalcaemia or MEN. Other biochemistry results revealed hypokalaemia of 3.2 mmol/l, low vitamin D at 16 ...

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...
