In the UK, ~1000 new patients are diagnosed with a pituitary tumour every year and 4.2% of all paediatric tumours are craniopharyngiomas. Although these tumours are predominantly benign, untreated they can lead to visual compromise, raised intracranial pressure and the endocrine effects of hypersecretion or hypopituitarism, resulting in significant morbidity and mortality. This talk provides an overview of the presentation and management of pituitary tumours and craniopharyngi...

Introduction: Pituitary apoplexy presents as a medical emergency, and usually occurs in people with pituitary macroadenomas. Immediate multidisciplinary expertise and timely intervention is needed to mitigate the associated morbidity. There is controversy regarding the role and the timing of neurosurgical intervention versus conservative management approach to obtain best visual and endocrine outcomes. Here we present a case of a man presenting with pituitary apoplexy and mana...

Langerhan cell histiocytosis (LCH) is a rare; incidence 1.8/100 000. It affects bone, skin, and pituitary but can involve any organ. Diabetes insipidus (DI) is reported in 15–50% of patients, and anterior pituitary dysfunction in 5–20%. We describe a patient whose diagnosis was delayed because of the challenge in making a tissue diagnosis.A 42-year-old female presented in 2010 with sudden onset deafness and vertigo then 1 year later developed D...

Background: Silent corticotroph adenomas (SCAs) are considered to be clinically silent and non-secreting but exhibit positive adrenocorticotropic hormone (ACTH) immunostaining. Whether, SCAs behave more aggressively than other non-functioning adenomas, remains controversial. We characterized our tertiary centre cohort of SCA patients, compared them to gonadotroph adenomas (GAs) and assessed for features predictive of recurrence.Objective: To compare char...

Introduction: Cushing’s disease is usually caused by functional corticotroph microadenomas of the pituitary. Crooke’s cell adenomas are rare, representing approximately 2% of corticotroph adenomas and mostly present as aggressive macroadenomas. Pituitary adenomas showing immunoreactivity for both ACTH and GH are also very uncommon. We present two cases of Cushing’s disease caused by macroadenomas with Crooke’s cell cha...

Introduction: Incompletely controlled acromegaly has a three-fold excess all-cause mortality, with stroke being the predominant cause of death. Debate exists about the relationship between fractionated radiation (FRT) and risk of stroke, with radiation damage to cerebral vasculature potentially being a cause. We present outcomes in patients treated by gamma knife STRS at the National Centre for Stereotactic Radiosurgery in Sheffield, with...

Introduction: Trans-sphenoidal Surgery (TSS) remains the primary treatment for acromegaly in most patients, but no previous data exist on outcomes for patients treated with gamma knife radiosurgery (STRS) as a primary treatment.Methods: 20 patients with acromegaly underwent primary STRS at the National Centre for Radiosurgery, Sheffield, UK between 1985 and 2015. Data collection: note review, database, laboratory results, patient questionnaire, and death...

Introduction: Xanthogranulomatous hypophysitis (XGH) is a very rare form of pituitary hypophysitis that may present both clinically and radiologically as a tumour. Our case series compares paediatric and adult presentations of XGH.Case series: Patient 1: A 15-year-old female presented with refractory headache, lethargy, short stature, delayed growth (weight (−3.36) SDS, height (−1.73) SDS, BMI 14 kg/m2), and pubertal arres...
