1/4. hypothyroidism caused by a nonvisible lingual thyroid.BACKGROUND: lingual thyroid is a developmental anomaly caused by failure of migration of the thyroid gland to its normal position in the neck. This anomaly is usually manifested in childhood as hypothyroidism or local symptoms. methods: We present a case of a 32-year-old patient in whom lingual thyroid was diagnosed after complaints of a chronic cough. Thyroid-stimulating hormone levels were significantly elevated. Sonograms of the neck revealed atrophy of both thyroid lobes, with nonhomogeneous consistency and no lymphadenopathy. technetium-99m scan revealed uptake at the tongue base, with no uptake at the neck or other locations. RESULTS: L-thyroxine treatment was begun, with progressive decrement in thyroid-stimulating hormone levels and cessation of the cough. CONCLUSION: This case is unique in both the advanced age of the patient and the unusual clinical presentation.- - - - - - - - - - ranking = 1keywords = tongue (Clic here for more details about this article) |
2/4. Obstructive lingual thyroid causing sleep apnea: a case report and review of the literature.lingual thyroid has been reported to cause obstructive sleep apnea (OSA) only once in the literature. We present a case of a 49-year-old nonobese female with a 2-year history of progressive snoring, apneas, snort arousals, and daytime somnolence associated with the sensation of an 'enlarging tongue'. She was found to have severe OSA caused by a large lingual thyroid. While positive airway pressure therapy was not successful, surgical resection of the thyroid was curative. OSA caused by lingual thyroid and other oropharyngeal/parapharyngeal tumors are discussed. A careful oropharyngeal examination is important in evaluating patients with complaints of OSA.- - - - - - - - - - ranking = 1keywords = tongue (Clic here for more details about this article) |
3/4. lingual thyroid--a lesson to learn.We present a case of a middle-aged woman with a mass in the posterior third of the tongue which was diagnosed as a tongue haemangioma. The tumour was successfully excised via a midline mandibular osteotomy and tongue splitting approach. The histopathology examination, however, revealed the 5x4 cms mass to be a lingual thyroid. The salient features of this unusual presentation of a thyroid enlargement will be discussed.- - - - - - - - - - ranking = 3keywords = tongue (Clic here for more details about this article) |
4/4. Ectopic lingual thyroid.Ectopic lingual thyroid is an uncommon embryological aberration characterised by the presence of thyroid tissue located in a site other than the normal, pretracheal region. The tongue is the most frequent ectopic location of the thyroid gland; the clinical incidence of lingual thyroid varies between 1:3000 and 1:10,000. We present a new case of lingual thyroid in a 10-year-old child who presented dysphagia. The radiological findings and the biopsy confirmed the diagnosis. As the mass was well tolerated, surgery was not indicated. At this time, there are no signs of complications or malignant transformation.- - - - - - - - - - ranking = 1keywords = tongue (Clic here for more details about this article) |
