The parathyroid adenoma: an imaging/surgical perspective.
The clinical picture of hyperparathyroidism has changed since the implementation of routine serum calcium testing, resulting in more asymptomatic patients undergoing early surgical exploration. Although operative complications (e.g., recurrent laryngeal nerve paralysis, hypocalcemia, etc.) are not prevalent, the risk can be minimized by minimizing tissue dissection. For this reason, we feel that preoperative tumor localization is of great importance. We report our imaging results of parathyroid adenomas, utilizing ultrasonography, technetium-thallium subtraction scanning, digital subtraction angiography and magnetic resonance imaging. We also present an imaging protocol which, we have found, maximizes preoperative identification of these tumors.
