“…In sporadic case reports, ectopic thyroid glands showed a signal intensity slightly higher than that of muscle tissue both on T1‐weighted and T2‐weighted images and similar to the signal intensity of the normal thyroid gland (4, 5, 7). In our series, ectopic glands appeared as well‐defined masses of isointense or hyperintense signal as compared to that of muscle tissue on T1WIs and low to intermediate signal on T2WIs although frequently associated with small cystic portions.…”

“…There are few case reports on MR appearances in this clinical condition (4, 5, 7). However, to our knowledge, there is no literature in which MR findings of lingual thyroid were compared to those of other disorders occurring in the submucosal areas in the base of the tongue.…”

Chondrosarcoma of the head and neck is relatively rare. We report the sixth case known to us in which the chondrosarcoma had originated in the hyoid bone. The patient, a 66-year-old man, underwent surgery. The resected tumour was a 5 cm encapsulated lesion composed of lobulated, firm, gray-white tissue. Histologically it showed mature chondrocytes without capsular invasion. There was high cellularity and a few binucleated chondrocytes. Although the tumour grade was prognostic significance, our literature review of the five other cases suggests that the location of the primary lesion and the adequacy of its resection to be more important. Our patient continues to do well 15 months post-operatively. However, long-term follow-up is essential as recurrences have been reported even after eight or 10 years.

“…Technetium-99 scanning and iodine-121 scanning should be performed to show the radionuclide activity at the level of the mouth and at the level of the normal position of the thyroid in the neck. Computed tomography and magnetic resonance imaging [16,25] make it possible to estimate the gland size and position. Because of the location of the mass in our case, in the dierential diagnosis before surgery we took into consideration the possibility of ectopic thyroid tissue.…”

Ectopic Lingual Thyroid as Unusual Cause of Severe Dysphagia

et al. 2001

View full text Add to dashboard Cite

Ectopic lingual thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue located in a site different from the pretracheal region as in the normal. Lingual thyroid is the most frequent ectopic location of the thyroid gland, although its clinical incidence varies between 1:3000 and 1:10,000. We present the case of a 26-year-old woman who presented severe dysphagia caused by a mass located on the base of the tongue in the midline. An endoscopic partial removal of the ectopic tissue allowed her to rapidly regain her swallowing capacity. The literature regarding the incidence and diagnosis of lingual thyroid is reviewed and the possibilities of treatment discussed.
