Background: It has been proposed that menopause has a beneficial effect on the natural history of hyperprolactinaemia attributed to prolactinoma. Nonetheless, series systematically assessing outcome in females with prolactinoma who have passed through menopause are very limited.Aim: To investigate the impact of menopause on prolactinomas in patients not on dopamine agonist (DA) treatment.Patie...

Introduction: Most prolactinomas in females are diagnosed during the years of reproductive age and the majority are microadenomas. Prolactinomas diagnosed after menopause are very rare with limited published data on their presentation and outcomes.Aim: The aim of our study was to assess the presenting clinical, biochemical and imaging findings, as well as the outcomes of women diagnosed with a prolactinoma in the post-menopausal period.<p class="abst...

Background: Isolated pituitary stalk (PS) lesions/thickening detected on imaging pose challenging dilemmas.Aim: Audit the diagnostic approach and management of patients with isolated PS lesions/thickening reported on MRI in a tertiary hospital.Methods: Reports of pituitary/brain MRIs performed in our Radiology Department between 1/2013 and 12/2015 were searched for the terms ‘stalk’, ‘infundibular’, ‘infund...

Aberrant adrenal LH expression is a rare cause of adrenal Cushing’s syndrome (CS) leading to transient hypercortisolism during pregnancies and ACTH-independent macronodular adrenal hyperplasia (AIMAH) after the sustained postmenopausal increase of LH secretion. Subclinical CS due to aberrant LH expression has very rarely been described. Herein, we report a case with aberrant LH/hCG adrenal receptor mediated subclinical CS in a patient with incidentally discovered AIMAH an...

Introduction: Despite the significant risk of regrowth of non-functioning pituitary adenomas (NFAs) after primary treatment, systematic data on the probability of further tumour progression and the effectiveness of management approaches are lacking.Aims: Assess the probability of further regrowth(s), predictive factors and outcomes of management approaches in patients with NFA diagnosed with adenoma regrowth after primary treatment (surgery combined or n...

Background: Current conclusions on risk of second brain tumour following radiotherapy for pituitary adenoma or craniopharyngioma are challenged methodologically by small patient sample size, selection biases or lack of appropriate controls.Objective: To ascertain whether radiotherapy for pituitary adenoma or craniopharyngioma is associated with increased second brain tumour risk, through use of appropriate methodology.Design: Multi...

Background: The risk of a second brain tumour following radiotherapy for pituitary adenoma or craniopharyngioma in adults is currently unclear. Studies are methodologically limited by small patient sample size, few case events, selection biases or the use of inappropriate controls.Objective: To ascertain whether radiotherapy delivered to adults with pituitary adenoma or craniopharyngioma is associated with an increased second brain tumour risk using appr...
