Sonography of intrathyroid parathyroid adenomas: are there distinctive features that allow for preoperative identification?
The purpose of our study was to determine if intra-thyroid parathyroid adenomas can be accurately identified by applying proposed criteria to preoperative ultrasound examinations in patients with primary hyperparathyroidism. ⋯ Application of specific ultrasound criteria facilitates pre-operative diagnosis of intra-thyroid parathyroid adenomas and facilitates surgical planning. This large series confirms previous, largely anecdotal reports of ultrasound's utility in detecting intra-thyroid parathyroid adenomas.
