The diagnosis of primary hyperparathyroidism (PHP) is chemical: high level of Parathormone (PTH) in conjunction with hypercalcaemia. In borderline cases with sub-normal plasma PTH and calcium, an oral calcium load test could allow a differential diagnosis from other causes of high PTH. Imaging is required only for PHP. Selective venous sampling can help in localizing a parathyroid adenoma in difficult cases by PTH cartography in the following situations: imaging in favour of an ectopic mediastinal gland or a deep cervical adenoma, persistent or recurrent PHP after first failed surgery with negative neck exploration or unsatisfactory in case of another hypersecreting gland, PHP well diagnosed with indeterminate imaging, symptomatic PHP with normal PTH and negative imaging. Venous blood sampling performed in a vascular radiological department with a quick PTH assay can reveal an area of maximum secretion potentially linked to a nodule localized by previous ultrasound coupled to scintigraphy, giving thus a "biological imaging" study. The association of imaging and biology is an efficient procedure enabling localization of an area of abnormal PTH secretion and characterization of the level of PTH secretion. The area with the highest gradient of PTH concentration can help to protocol CT and MR examination.
