IMAGING FEATURES OF ULTRASOUND IN THE DIAGNOSIS OF PARATHYROID TUMORS
Main Article Content
Abstract
A retrospective study was conducted at Bach Mai hospital with the aim of studying imaging features and the role of parathyroid tumors on ultrasound.
Results: There were 33 patients with primary hyperparathyroidism who had available preoperative ultrasounds of the parathyroid glands. At surgery, 42 parathyroid adenomas were removed in the 33 patients. Ultrasound correctly revealed 38 adenomas in 42 parathyroid adenomas (90.47%). The most common parathyroid adenomas were located on the posterior of the thyroid lobes (97.4%). All of parathyroids adenoma had well-defined margins (100%) and most showed hypoechogenicity (71.1%), and peripheral vascularity was the most common pattern (92.1%).
Conclusion: The most common ultrasonographic findings of parathyroid adenomas was well-defined hypoechoic lesion with peripheral vascularity. Ultrasound plays role in pre-operative localization of the parathyroid tumors and supporting clinical diagnosis.
