“…Surgical treatment remains the only curative option. Despite this fact, there is still a considerable delay of several years between diagnosis of pHPT and parathyroidectomy, ranging from 3.9 to almost 5 years [7, 8].…”

Background Primary hyperparathyroidism (pHPT) is well treatable surgically. Sonography (US) and sestamibi scintigraphy (MIBI) are used routinely, but it is unclear how valuable they are in determining Parathyroid glands’ different locations. This study aimed to evaluate the prognostic value of US and MIBI in relation to the different localization of parathyroid adenomas in one of the largest study populations analyzed to date. Methods 1089 patients with pHPT who had treatment in one tertiary referral center between 2007 and 2016 were analyzed. Preoperative US and MIBI reports were compared with the parathyroid adenoma's intraoperative localization. All parathyroid glands were confirmed by histological diagnosis. Results No gland was detectable in 22.5% and 27.7% of all patients, by US or by MIBI, respectively. In relation to the different adenoma locations, the sensitivity of US ranged from 21.3% (upper right) to 68.9% (lower left) and of MIBI ranged from 23.5% (upper right) to 72% (lower left). The specificity for US ranged from 85% (lower right) to 99.2% (upper right) and for MIBI ranged from 86.1% (lower right) to 99.1% (upper right. Positive predictive values for all gland sites were 54% and 59% for MIBI and US, respectively. The value increased for side‐only prediction to 73% and 78%, respectively. Neither the parathyroid hormone level nor the calcium value level influenced the sensitivity or specificity of the two test methods. Conclusions The validity of preoperative US and MIBI depends crucially on the specific localization of adenomas. This should be considered when planning the extent of parathyroid surgery.
