Acromegaly due to an ectopic pituitary adenoma in the clivus: case report and review of literature.

abstract：:Double pituitary adenomas are rare in surgical specimens and the most common clinical feature in reported patients has been acromegaly. We report 3 cases of double pituitary lesions in patients who presented with Cushing's disease. In a 22-year-old man (case 1) with delayed puberty and low testosterone levels, mild hy...

abstract：PURPOSE:Recent guidelines suggest that a single prolactin measurement is adequate to confirm hyperprolactinaemia. This may lead to unnecessary investigation of artefactual hyperprolactinaemia. Prolactin measurement drawn from an indwelling cannula after rest removes stress as a confounding variable.
