摘要

Primary hyperparathyroidism is a biological diagnosis. The reference treatment is surgery. When minimally invasive surgery is considered, it is recommended to perform a cervical ultrasound and a scintigraphic examination to localize the hypertrophied parathyroid glands. The multiphasic scanner (4D CT) is a very effective examination to detect and locate precisely the parathyroid adenomas. The study of densities makes it possible to differentiate the adenoma from the thyroid and the lymph nodes that are the differential diagnoses. Without injection, the adenoma is more hypodense than the thyroid with a threshold set at 75 UH. On the early phase after injection, the adenoma appears very hypervascularized with a density > 114 UH. The ganglion appears hypovascularized with a density < 114 UH. In the late phase, there is a decrease in the density within the adenoma, while density within the ganglion increases. The parathyroid scan is indicated in case of negativity or discordance of the couple ultrasound scintigraphy. It is also strongly recommended, in case of persistence or recurrence of hyperparathyroidism after surgery, as well as to better study a parathyroid ectopy. (C) 2017 Elsevier Masson SAS.
