Large corticotroph adenomas are uncommon pituitary mass lesions, representing around 10% of cases of Cushing's disease, and are often found to be locally invasive. 'Silent' corticotrophinomas stain for ACTH, but do not secrete sufficient ACTH to cause Cushing's disease. We describe a patient with an unusual mass presentation of a pituitary adenoma in whom there was also a marked discrepancy between the clinical and laboratory findings in the assessment of suspected Cushing's d...

Pituitary apoplexy is a rare condition caused by haemorrhage or infarction into a pituitary tumour. The majority of patients do not have any identifiable triggering event, although situations altering the blood flow to the pituitary gland and pre-existing systemic hypertension have been identified as potential causal factors.We retrospectively reviewed the presentation and outcome of 15 patients with pituitary apoplexy (8 men, 7 women; age 16-87, mean 5...

We examined the results of treatment of adult Cushing's disease by transphenoidal surgery by a single neurosurgeon (MP). Patients with Nelson's syndrome and those who previously had received treatment for Cushing's by a different surgeon were excluded. We reviewed the pituitary database and patient records for all patients operated between 1988 and 2000 with clear pre-operative evidence of Cushing's disease. 117 patients had clear evidence of a pituitary source of excess ACTH....
