Less Invasive Surgery for Primary Hyperparathyroidism Based on Preoperative 99m Tc-hexakis-2-methoxyisobutylisonitrile Imaging Findings

Abstract

The sensitivity of MIBI to adenoma was thus found to be highly satisfactory. As a result, it might be possible to perform less invasive surgeries based on MIBI imaging without any decrease in the surgical results.

Preoperative evaluation of hyperparathyroidism: the role of dual-phase parathyroid scintigraphy and ultrasound imaging

“…There are reports stating that weight alone in sHPT does not account for the lesser likelihood of detection by MIBI; other factors such as fewer mitochondria, poor vascularity, and altered metabolic conditions seen in patients suffering from chronic renal disease could have led to the inadequate distribution and concentration of MIBI [43,44]. Our study seems to favor the contention of other authors who have suggested that a signifi cant correlation exists between scintigraphic fi ndings and the size/weight of the glands [32,45,46]. In our study, non-signifi cant differences in the weight of the glands between pHPT and sHPT could have led to similar sensitivity values in this different clinicopathologic setting.…”

Uncommon Ectopic Parathyroid Adenoma

“…Pulmonary lipomas within the peripheral parenchyma are exceedingly rare. 2, 3 We report such a case.…”

“…Ectopic parathyroid adenomas of less than 10 mm in diameter are best detected with 99m Tc-MIBI scintigraphy. 3 Cervical ultrasound, CT and magnetic resonance imaging are used to determine the exact anatomical site of the mass.…”

A Case of a Retroesophageal Parathyroid Adenoma with an Aberrant Right Subclavian Artery: A Potential Surgical Pitfall

“…Taira, et al reported the usability of high-resolution CT with 99m Tc-MIBI scintigraphy for the detection of ectopic mediastinal parathyroid adenomas less than 10 mm in diameter. 6) We identified the ectopic adenoma using both 99m Tc-MIBI scintigraphy and conventional chest CT.…”
