Abstract
Background
Parathyroidectomy is the only curative treatment for primary hyperparathyroidism (PHPT). Ultrasound (US) and technetium-99 m sestamibi (99mTc-MIBI) scintigraphy are recommended as the first-line localization imaging modalities for PHPT in adults, but the value of preoperative imaging in pediatric patients has not been reported.
Objective
To evaluate the added value of 99mTc-MIBI scintigraphy in pediatric PHPT patients with positive ultrasound results.
Materials and methods
Pediatric patients (≤18 years old) who were diagnosed with PHPT and underwent surgical treatment in Peking Union Medical College Hospital between January 2003 and January 2021 were included in this study. Demographic and clinical characteristics, preoperative localization US, 99mTc-MIBI scintigraphy and pathology results were collected. Preoperative localization results were evaluated by comparison with surgical and pathological findings.
Results
There were 32 pediatric PHPT patients with median age of 14.7 ± 2.5 years who all proved to have single-gland disease without ectopic lesions. The median lesion size was 2.85 cm (range 1.0–5.8 cm). All patients underwent US and 99mTc-MIBI scintigraphy. Neck US demonstrated 100% sensitivity. Of 32 patients with a positive US, 99mTc-MIBI scintigraphy was concordant in 30 (93.8%). In 2 patients (6.3%), US reported suspected multigland disease, which was correctly diagnosed by 99mTc-MIBI scintigraphy as single lesions.
Conclusion
In pediatric PHPT patients, US achieved high sensitivity for preoperative localization. 99mTc-MIBI scintigraphy for pediatric patients with positive US results would not increase the sensitivity. Implementation of 99mTc-MIBI scintigraphy could increase the specificity in pediatric patients with multigland disease suspected by US.
