“…Regarding intrathoracic (mediastinal) location, we found only 7 cases in the literature. In 5 of those cases, the ectopia was located in the anterior mediastinum, (8,(11)(12)(13) as in the cases reported here, and, in 2, (12,14) it was located posteriorly. Therefore, although entirely intrathoracic ectopic goiters are rare, they have to be considered in the differential diagnosis of all mediastinal masses.…”

“…However, not all ectopic thyroid deposits can be explained by ed underneath the left lobe of the thyroid in the lower cervix, which is a rare location. Other rare locations of ectopic thyroid have been described in the submandibular region 4,5 , parotid salivary gland 6 , trachea 7 , laterally to the carotid arteries and jugular veins 3 , mediastinum 8 , heart 9 , lung 10 , duodenum 11 , adrenal gland 12 and uterus 13 .…”

Ectopic thyroid tissue in the lower neck with a coexisting normally located multinodular goiter is a rare entity. We present a 27-year old asymptomatic woman with a recent history of a painless mass in the left side of her lower neck. Thyroid function tests were normal. An ultrasound of her neck showed a multinodular goiter and a 3.4 cm solid mass in the left lower cervical area. These findings were confirmed by an MRI scan of her neck. The Tc99m Pertechnetate scan showed the presence of a functioning area under the left lobe of the thyroid gland. The patient underwent surgery. The cervical mass was identified as a structure separate from the left lobe of the thyroid, without any attachments to the body of the gland and was uniformly resected. A subtotal thyroidectomy was also performed. The histology revealed that the separate structure represented ectopic thyroid tissue. The patient had an uneventful postoperative recovery, subsequent to which she was euthyroid and had normal calcium levels.

“…True ectopic thyroid in the thorax are encountered in less than 1% of all intarthoracic goiter [3,4]. Ectopic thyroid tissue is the result of aberrant embryogenesis of the thyroid gland during its passage from the floor of the primitive foregut to its pretracheal position.…”

Mediastinal ectopic thyroid is quite rare, occurring in less than 1% of all ectopic thyroids. Frequent location of mediastinal ectopic thyroid in reported cases is anterosuperior mediastinum. CT findings of ectopic thyroid can be various and are dependent on several factors, such as its iodine content, the extent of tissue degeneration, and the presence of colloid cysts. This is a case of right paratracheal ectopic thyroid with nodular hyperplasia, mimicking metastatic nodal mass on both CT and 18 F-FDG PET CT in a patient with colon cancer.
