The aetiology of thyroid nodules is due to the interaction between genetic and environmental factors. Thyroid nodules are common. Epidemiological studies suggest that 1% of men and 5% of women have thyroid nodules detected clinically and that the frequency increases with age and in iodine-deficient populations. With the increasing use of sensitive imaging techniques, an increasing proportion of thyroid nodules are detected incidentally. Up to 50% of nodules >1 cm detected ...

Background: Incidentally discovered pituitary lesions are a common problem in the endocrinology clinic due to increased access to detailed brain imaging. The challenge for endocrinologists is to determine which pituitary lesions are clinically significant and which are truly incidental. Pituitary micro-adenomas have been found at autopsy in 1.5–27% of subjects, whilst population-based radiological studies report small pituitary lesions in ~10%. It is difficult to produce ...

The widespread use of abdominal CT/MRI has resulted in a new and common diagnosis for the clinical endocrinologist – the management of patients with adrenal incidentalomas. Defined as an adrenal mass discovered incidentally in the work-up or treatment of clinical conditions not related to suspicion of adrenal disease, incidentalomas cover a spectrum of underlying adrenal pathologies with a common pathway of discovery. Because of the risk of malignancy, they raise uncertai...
