99mTc Sodium Pertechnetate Uptake in Ectopic Mediastinal Thyroid Tissue on Hybrid Thyroid Scintigraphy. 2018

Maimoona Siddique, and Humayun Bashir

Ectopic thyroid is a rare/incidental imaging finding. When discovered, 90% of ectopic thyroid is found typically along the pathway of embryologic migration of thyroid tissue, whereas around 10% have been discovered in other anatomical locations including the mediastinum and the heart. Thyroid scintigraphy with Tc sodium pertechnetate (TcO4) is peculiar for thyroid tissue uptake. The current case, clinically euthyroid, had heterogeneous uptake in multinodular goiter with uptake in the ectopic thyroid tissue in right paratracheal location on functional imaging with TcO4. Subsequent single photon emission computed tomography/computed tomography (SPECT/CT) imaging confirmed the ectopic thyroid tissue.

D013961	Thyroid Gland	A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
