Abstract
Background
Focused parathyroidectomy in primary hyperparathyroidism is possible with accurate
preoperative localization. A growing body of data exists regarding the role of radio-labeled
C11 choline positron emission tomography/computed tomography. In cases of nonlocalized
disease, it may be a useful adjunct to ultrasound, (123)I/(99)Tc-sestamibi (I-123
sestamibi), or 4-dimensional computed tomography imaging.
Methods
Patients who received a neck and chest limited coverage C11 choline positron emission tomography/computed tomography for evaluation of primary
hyperparathyroidism from 2017 to 2021 at a single institution were retrospectively
reviewed. We assessed the sensitivity, positive predictive value, and false negative
rate. We also compared these rates to the standard modalities of ultrasound, I-123
sestamibi, 4-dimensional computed tomography, and examined concordance rates.
Results
We identified 43 patients, of whom 33 had a positive C11 choline positron emission tomography/computed tomography finding. This cohort of
patients had failed to localize on multiple standard imaging modalities. Twenty-five
patients proceeded to surgery, 72% of whom were reoperative cases. Twenty (80%) achieved
an intraoperative cure. Analysis showed that C11 choline positron emission tomography/computed tomography achieved a sensitivity of
64% (95% confidence interval 47%–82%) and positive predictive value of 72% (95% confidence
interval 54%–90%). There were 5/25 (20%) false positive positron emission tomography
C11 choline results found to be lymph nodes, normal parathyroid, and 1 recurrent laryngeal
nerve neuroma.
Conclusion
C
11
choline positron emission tomography/computed tomography is a useful adjunct for
parathyroid localization in a complex population of patients who have failed standard
localization techniques including ultrasound, I-123 sestamibi, or 4-dimensional computed
tomography and/or prior operations. Although routine inclusion of C11 choline positron emission tomography/computed tomography imaging may not be necessary,
it may aid in preoperative localization in the reoperative setting.To read this article in full you will need to make a payment
