Sho S, et al. - This work was designed to characterize factors associated with missed parathyroid lesions on preoperative 4-dimensional computed tomographic scans (4D-CTs) and to investigate patterns of commonly observed errors. Multigland disease had the most strong association with discordance between preoperative 4D-CTs and intraoperative findings, followed by parathyroid lesion in the inferior position and parathyroid lesion size of 10 mm or less. They recommended surgeons to be aware of these potential pitfalls to better leverage this new localization technique in preoperative planning and intraoperative troubleshooting.
