title: High-resolution ultrasound-guided percutaneous needle biopsy and intraoperative ultrasonography of a cervical parathyroid adenoma in a patient with persistent hyperparathyroidism.
abstract: We present a case of persistent hyperparathyroidism in which high-resolution real-time ultrasonography was used to perform a percutaneous needle biopsy of a parathyroid tumor. Additionally, intraoperative ultrasonography was valuable in the precise localization of the tumor and thereby reduced the need for extensive surgical reexploration.
