title: Identifying an Ectopic Parathyroid Adenoma Using 4DCT in a Pediatric Patient with Persistent Primary Hyperparathyroidism.
abstract: We present a case of an ectopic mediastinal parathyroid adenoma detected with 4-dimensional computed tomography (4DCT) in a patient with persistent primary hyperparathyroidism and failed neck exploration. We discuss the utility of 4DCT in the localization of these lesions and offer an algorithm that implements the use of 4DCT early on when standard imaging techniques are nonlocalizing.
