Intrathyroid Parathyroid Adenoma Appearance on FCH PET/CT Imaging.

Intrathyroid parathyroid adenomas can be difficult to detect on imaging and may be missed intraoperatively. 18F-fluorocholine positron emission tomography/computed tomography (FCH PET/CT) is a relatively new imaging modality used to evaluate patients with hyperparathyroidism preoperatively. We present the case of an intrathyroid parathyroid adenoma visualised on FCH PET/CT but not identified on the current conventional imaging modalities preoperatively, which subsequently underwent successful surgical removal.
