Hyperparathyroidism can lead to symptoms related to hypercalcemia and warrant treatment, which is often surgical. Evaluation of the parathyroid glands with sonography requires knowledge of the classic and variant appearances of parathyroid lesions as well as the range of anatomic locations in which they may occur. The accuracy of ultrasonography in characterizing parathyroid disease is augmented by correlation with scintigraphy; although neither sonography nor scintigraphy excels in detecting multigland disease or after failed resection, they are still used in those settings, with varying sensitivities reported in the literature. Because of the increasing use of minimally invasive techniques, ultrasonography, and when appropriate, ultrasound-guided fine-needle aspiration, play a crucial role in preoperative characterization of abnormal parathyroid glands.
