Preoperative localization modalities in primary hyperparathyroidism: Correlation with postoperative cure

An ultrasonography performed by an experienced surgeon is an extremely valuable preoperative localization modality. The cure rate obtained is proportional to the number of positive imaging studies. In patients with negative ultrasonography performed by a nonexperienced radiologist and a negative sestamibi scan, the performance of computed tomography does not seem to increase cure rate. Patients with no positive preoperative scans represent a challenging subgroup, with cure rates of approximately 80%.
