Sensitive Detection of a Small Parathyroid Adenoma Using Fluorocholine PET/CT: A Case Report / 대한핵의학회잡지

ABSTRACT

Primary hyperparathyroidism is caused by parathyroid adenoma in the majority of cases and diagnosis is usually made biochemically. Pre-surgical localization of parathyroid adenoma is essential to limit the extent of surgery and avoid missing them at ectopic sites. Anatomical and functional imaging are used for the localization, but may fail to identify the small and ectopic parathyroid adenoma. We present a case of small sized ectopic parathyroid adenoma at unusual location detected by F-18 fluorocholine (FCH) PET/CT, where other imaging modalities failed. The post-operative histopathology confirmed the diagnosis of ectopic parathyroid adenoma.
