Concomitant thyroid lesions in patients with primary hyperparathyroidism

Summary Background Concomitant thyroid pathologies in patients with primary hyperparathyroidism (PHPT) present a challenge in the clinical and surgical decision-making for these patients. In this study, we aimed to evaluate concomitant thyroid pathologies in patients who underwent operations for PHPT to determine the sensitivity (Sn) of neck ultrasonography (US) and Tc99m sestamibi scintigraphy in detecting parathyroid adenoma. We also aimed to determine the clinical impact of preoperative neck US in patients with PHPT. Methods One hundred thirty-eight patients with PHPT were included in this retrospective study. All patients underwent preoperative Tc99m sestamibi scintigraphy and/or thyroid US. Nodules of ≥1 cm or
