“…Primary mediastinal goiter, i.e., a goiter with a separate blood supply originating from the mediastinal vessels, is rarely observed. This type of goiter accounts for less than 1% of surgical patients [6]. In the present series, the authors defined goiters as mediastinal when at least 50% of their mass was situated below the sternal notch and, additionally, when the lower pole of the thyroid lobe extended to or was situated below the aortic arch level.…”

“…This concept is supported by the very high percentage of sternotomies in recurrent goiter (p<0.05). Such aberrant adenomas that are loosely or not at all associated with the thyroid are rare, but they statistically more frequently require the extension of the surgical approach [6,7,17,20,22].…”

“…This type of goiter is vascularized by the mediastinal vessels, directly branching off the aortic arch, and poses a significant surgical problem. In the majority of cases, primary goiters are accessible through thoracotomies or sternotomies [6,7].…”

Surgical management of patients with mediastinal goiter is the therapeutic modality that requires considerable experience of the surgical team, performed in specialized centers, and appropriate preoperative diagnostic management. Statistically significant risk factors for sternotomy are as follows: recurrent goiter, primary mediastinal goiter, posterior mediastinal location of goiter, and the presence of an aberrant adenoma situated in the mediastinum.

A Case of Right Paratracheal Ectopic Thyroid, Mimicking Metastasis on CT and 18F-FDG PET CT

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.

“…The incidence of ectopic thyroid tissue is 1 in every 100,000 to 300,000 in general population 2 and lingual thyroid (first described by Hickman 3 in 1869) is the most common ectopic site (90%). 4 Lingual thyroid is common in females (80%). 5 In 70% of the cases, it is the only functioning thyroid tissue.…”

Lingual Papillary Thyroid Carcinoma with Bilateral Neck Node Metastasis

Incidence of ectopic thyroid tissue is 1 in every 100,000 to 300,000 in general population and lingual thyroid is the most common ectopic site (90%). The number of reported neoplasms occurring in this tissue seems disproportionately small when compared with the frequency of tumor formation in the normally placed thyroid. Till now only 51 cases of lingual thyroid cancer have been reported in the literature. We are reporting a case of lingual thyroid carcinoma with bilateral cervical metastasis and absent orthotopic thyroid gland. In our case we approach the tumor via midline lip splitting with lateral mandibulotomy approach which provides us a good exposure of the entire oropharynx (tumor). We have managed the tumor according to the guidelines of differentiated thyroid cancer because of non availability of guidelines for ectopic thyroid cancer. After surgical excision of lingual thyroid and neck dissection radioiodine therapy was given. The surgical approach to a lingual thyroid cancer as well as adjuvant therapy and natural history remains to be ascertained due to the rarity of the disease. Lip splitting with lateral mandibulotomy and swing approach appears to give adequate exposure to lingual thyroid. How to cite this article Singh SP, Das S, Jain DK.

Ectopic thyroid

Abstract: Primary mediastinal ectopic goiters are very rare. We report a case in which an ectopic goiter with blood supply from the thoracic vessels necessitated a transternal approach for removal, resulting in a favorable outcome.
