It is well recognised that excess vitamin D therapy leads to hypercalcaemia, and that this effect may be prolonged, lasting upto several weeks with some vitamin D preparations. We describe a case of severe, life threatening hypercalcaemia from vitamin D therapy, in which the duration of action of vitamin D was exceptionally long. A 51 year old lady presented with acute, severe haemorrhagic...

The requirement for Sestimibi imaging of the parathyroid glands has increased over recent years, partly due to advances in surgical techniques and the need for accurate pre-operative localisation. We audited sestimibi imaging to ensure efficient and appropriate use of this tool in the face of increasing demand. Over two and a half years 128 scans were identified by Nuclear Medicine. We obtained biochemistry and operative status for these using the hospital patient administrati...

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...
