Ectopic intrathyroidal parathyroid adenoma presented with multiple lytic bone lesions

Abstract

We report a rare case of intrathyroidal parathyroid adenoma (ITPA) of a 17-year-old girl with ectopic ITPA with diagnostic and therapeutic challenges due to the rare ectopic location and association with multiple lytic bone lesions. Parathyroid adenoma (PA) is the most common cause of primary hyperparathyroidism. It is a benign tumor and is generally presented as solitary adenoma. Identification of ITPA by imaging characteristics is sometimes difficult, being often an intraoperative discovery that requires special surgical strategy.
