“…Less commonly, patients may present with dysphagia or the superior vena cava syndrome. Intrathoracic thyroid may also be revealed incidentally on chest radiograph (34)(35)(36) or on autopsy (37). In cases of mediastinal ectopic thyroid, orthotopic tissue usually coexists and the patients are euthyroid (36).…”

“…Differential diagnosis of intratracheal ectopic thyroid includes other benign conditions, such as papilloma, enchondroma, osteoma, and amyloid deposits, as well as malignant diseases other than thyroid carcinoma, such as chondrosarcoma, squamous cell carcinoma, or lymphoma (32,77). Differential diagnosis for mediastinal thyroid includes germ cell tumors, neurogenic tumors, lymphomas, and thymic and mesenchymal tumors (36). Struma ovarii must be distinguished from primary ovarian tumors, such as granulosa cell tumors, Brenner tumors, papillary serous cystadenomas or cystadenocarcinomas, struma carcinoid, or rare cases of differentiated thyroid carcinoma metastatic to the ovary (78,79).…”

Ectopic thyroid tissue is a rare entity resulting from developmental defects at early stages of thyroid gland embryogenesis, during its passage from the floor of the primitive foregut to its final pre-tracheal position. It is frequently found around the course of the thyroglossal duct or laterally in the neck, as well as in distant places such as the mediastinum and the subdiaphragmatic organs. Although most cases are asymptomatic, symptoms related to tumor size and its relationship with surrounding tissues may also appear. Any disease affecting the thyroid gland may also involve the ectopic thyroid, including malignancy. The clinician must distinguish between ectopic thyroid and metastatic deposits emerging from an orthotopic gland, as well as other benign or malignant masses. Thyroid scintigraphy plays the most important role in diagnosing ectopy, but ultrasonography contributes as well. In cases of symptomatic disease, surgery is the treatment of choice, followed by radioiodine ablation and levothyroxine suppression therapy in more refractory cases. This review provides current understanding about the wide clinical spectrum of this rare condition, also referring to optimal diagnostic approach, differential diagnosis, and management strategies.

“…A thoracoscopic approach was the first choice in this case but transverse neck incision assistance was performed due to the incomplete exposure of the anterior mass. Ectopic thyroid should be considered during the diagnosis of mediastinal masses as there is a risk of hypothyroidism after surgery if the ectopic thyroid is nonfunctional [14]. …”

IntroductionEctopic thyroid is characterized by the presence of thyroid tissue in a site other than in its usual pretracheal region. It is a rare condition among the thyroid diseases. Dural ectopic thyroid present in the cervical and anterior mediastinal has not been reported.Case presentationA 45-year-old Chinese woman presented with a nonfunctional ectopic thyroid located both in the cervical and anterior mediastinum. The ectopic thyroid was removed under video-assisted thoracoscopic surgery using a transverse neck incision and her postoperative period has been uneventful thus far.ConclusionsEctopic thyroid is a rare condition among the thyroid diseases, and its location in the anterior mediastinum is even more uncommon. Less than 15 cases have been reported in the last four decades. This is the first case of ectopic thyroid to appear in both the cervical and anterior mediastinum at same time. Masses in the anterior mediastinal are usually thymoma, lymphoma, pheochromocytoma and germ cell tumors. Ectopic thyroid in this area is quite rare so this case enhances our understanding of the diagnosis of mediastinal masses.

“…It is observed through radiation screening and CT scans and is reported to cause dry cough, dyspnea, hemoptysis aphagia, and superior vena cava syndrome. In addition, it is reported that orthotropic thyroid coexists in all cases of intrapulmonary thyroid [4,5]. Radiologic examinations for diagnosis include CT, magnetic resonance imaging, Tc-99m, I-131, and I-123.…”

An ectopic thyroid is caused by abnormalities in migration of the thyroid during development and rarely occurs in the thoracic cavity or the abdominal cavity. We report the case of a 64-year-old female who had abnormal findings from a thyroid hormone test during follow-up after thyroid cancer surgery. Based on the radioisotope diagnostic test, an ectopic thyroid inside the thoracic cavity was suspected. Through surgical treatment, the patient was diagnosed with ectopic intrapulmonary thyroid. Ectopic intrapulmonary thyroid is reported to be very rare and the case is described along with a literature review.
