[18F]Fluorocholine PET/CT in a 15-year-old patient suggested HPT-JT syndrome with active cemento-ossifying fibroma

To our knowledge, this is the first reported case utilizing [18F]Fluorocholine PET/CT for the evaluation and management of HPT-JT syndrome with active presence of a maxillary cemento-ossifying fibroma. Given its superior sensitivity compared to conventional imaging, [18F]Fluorocholine PET/CT provided critical information for surgical planning and it might be a useful diagnostic tool for long-term disease monitoring. This case highlights the potential role of [18F]Fluorocholine PET/CT in detecting both parathyroid and jaw manifestations of HPT-JT syndrome, emphasizing the need for further research into its application in hereditary endocrine disorders.
