Ectopic Thyroid Tissue

Cryptothyroidism


Presentation

  • We present the case of a thirteen year old male child with a midline cervical mass first noted at one year of age.[ncbi.nlm.nih.gov]
Euthyroid
  • Most of such patients are euthyroid or mildly hypothyroid. Thyroid ectopia often resides in lingual, sublingual and subhyoid areas.[ncbi.nlm.nih.gov]
  • All PH patients were treated with thyroid hormone to maintain euthyroidism.[journals.plos.org]
Recurrent Chest Pain
  • In our patient, a 42-year-old woman with recurrent chest pain, two spheric cardiac tumors were diagnosed by transthoracal echocardiography. One of the tumors, obstructing the LVOT, could successfully be resected under cardiopulmonary bypass.[ncbi.nlm.nih.gov]
Hand Tremor
  • They may include Being nervous or irritable Mood swings Fatigue or muscle weakness Heat intolerance Trouble sleeping Hand tremors Rapid and irregular heartbeat Frequent bowel movements or diarrhea Weight loss Goiter, which is an enlarged thyroid that[icdlist.com]

Workup

  • We describe the presentation, workup, surgical management, and brief review of the literature. Retroactive review of an 83-year-old white female patient record. As a case report, this project was exempt from institutional review board approval.[ncbi.nlm.nih.gov]
  • Elsevier Health Sciences, ١٣‏/٠٨‏/٢٠١٢ - 736 من الصفحات Master all the relevant anatomy, surgical procedures, and workup needed for residency, and learn to manage the difficult cases encountered by experienced surgeons.[books.google.com]
Superior Mediastinal Mass
  • Computed tomographic angiography ruled out pulmonary embolism but fortuitously revealed a right lateral superior mediastinal mass in the pretracheal retrocaval space measuring 43 35 27 mm.[em-consulte.com]
Posterior Mediastinal Mass
  • Perithyroid thyroid follicles Images hosted on other servers: Benign conditions Ectopic vs. orthotopic thyroid Posterior mediastinal mass Adrenal mass Adenoma, ectopic thyroid PTC arising in ectopic thyroid Virtual slides Images hosted on other servers[pathologyoutlines.com]
Dyslipidemia
  • Past history included hypertension treated with irbesartan and dyslipidemia treated with fenofibrate.[em-consulte.com]

Treatment

  • To evaluate the sensitivity of US in the detection of such ectopias and to describe their US pattern before and during treatment.[ncbi.nlm.nih.gov]
  • Depending on the position of the tissue, sternotomy or thoracotomy can be performed for surgical treatment. Also, thoracoscopic treatment can also be considered.[casereports.in]

Prognosis

  • Once a careful histological examination has revealed a follicular adenoma, the prognosis is good especially if successful surgical excision is part of the management.[ncbi.nlm.nih.gov]
  • […] with regular margins, rare cystic degeneration, and without calcification ( Arch Endocrinol Metab 2015;60:231 ) Radiology images Images hosted on other servers: Neck ultrasound Head MRI Chest CT Abdominal MRI Intracardiac thyroid Prognostic factors Prognosis[pathologyoutlines.com]
  • Prognosis Without treatment thyroid ectopia results in severe intellectual deficit and short stature. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Complications and prognosis Mild hyponatraemia is associated with gait disturbance in the elderly and with falls.[patient.info]
  • No patients with PTC of TGDC reviewed by Patel et al. ( 41 ) exhibited disease-related deaths over a 10-yr period, suggesting that TGDC PTC has an excellent prognosis with appropriate treatment.[academic.oup.com]

Etiology

  • The etiology is related to the embryological development and maturation of the thyroid gland. It is important to consider metastatic thyroid carcinoma when ectopic thyroid tissue is identified.[ncbi.nlm.nih.gov]
  • Thoroughly revised and extensively expanded, this encyclopedic, highly acclaimed title addresses all aspects of the etiology, pathogenesis, diagnosis, initial treatment and long-term management of all varieties of thyroid cancer.[books.google.com]

Epidemiology

  • Gross vs. microscopic True vs. mimickers (metastasis, parasitic nodule, see Differential Diagnosis ) Epidemiology The most frequent form of thyroid dysgenesis, accounting for 50% of cases ( Endocr Rev 2004;25:722 ) Several hundred cases of ectopic thyroid[pathologyoutlines.com]
  • Lateral Neck Ectopic Thyroid Cancer Epidemiology and clinical presentation Precise epidemiological data regarding the incidence and prevalence of lateral neck ectopic thyroid cancer are lacking because it is often extremely difficult to distinguish primary[academic.oup.com]
  • Summary Epidemiology Prevalence is estimated at about 1/7,000. Thyroid ectopia causes around two-thirds of thyroid dysgenesis and is twice as common in females as in males.[orpha.net]

  • Epidemiology Hyponatraemia is the most common electrolyte abnormality encountered in clinical practice. An accurate incidence of mild hyponatraemia managed in the community is impossible, as it is rarely reported.[patient.info]

Prevention

  • […] it should not be forgotten that the identification of an agenesis of the isthmus as well as the other thyroid anomalies during the preoperative examination, will make a remarkable contribution in deciding the strategy of the surgery and will help in preventing[ncbi.nlm.nih.gov]
  • It is important to make sure the pyramidal lobe is removed during thyroidectomy, to prevent recurrence of goitre, Graves' disease or cancer in the remnant.[endocrinesurgery.net.au]
  • In order to prevent misdiagnosis and mismanagement, patients with a cervical mass in the anterior midline should be subjected to history screening, physical examination, cervical CDU, RI, thyroid function examinations (TSH, FT 3 and FT 4 ), FNA biopsy[spandidos-publications.com]
  • The relations of these vessels with the other structures are important for accurate diagnostic and invasive techniques and to prevent further complications during surgical interventions.[thefreelibrary.com]
  • Neverthless to prevent inadvertent removal of only functioning thyroid tissue and subsequent complications, they proposed routine preoperative USG in suspicious thyroglossal duct cyst.[indianpediatrics.net]
