چکیده

large median endodermal anlage and two lateral anlages (1). Commonly, the median anlage fails to descend, resulting in a lingual thyroid gland. In rare cases, failure of the lateral anlage to fuse with the median anlage produces a lateral ectopic thyroid gland (2). There are a number of case reports of papillary thyroid carcinomas in ectopic thyroid tissue, but there are only a few cases of primary follicular carcinoma in an ectopic thyroid gland (3, 4). We report here on the ultrasonography (US), computed tomography (CT) and magnetic resonance image (MRI) findings of a primary follicular carcinoma arising from ectopic thyroid tissue in the lateral neck. To the best of our knowledge, this is the first such case report with the findings of these three imaging modalities. Case Report

A Case of Lateral Neck Cyst with Ectopic Thyroid Papillary Carcinoma

Thyroid develops from median rudiment which is a surface elevation dorsal to the tuberculam impar and forms by proliferation of endodermal cells. Lateral thyroid element of the fourth pouch contributes in the development of thyroid gland.
