Abstract
|
|
|
Ectopic thyrod gland is relatively rare condition and a developmental anomaly characterized by an aggregated
of thyroid tissue. Usually it occurs along the path of descent of the developing thyroid primodium from the foramen
cecum, the commonest being lingual followed by sublingual and in the anterior midline of neck at, or
below, the level of the hyoid bone. It is unusual for lingual thyroid to present simultaneously with another ectopic
thyroid. It is extremely rare for two ectopic foci of thyroid tissue to present simultaneously. Only 2 dual
ectopic thyroid case with a normally located thyroid gland have been reported. We report a patient with dual
ectopic thyroid misdiagnosed as a metastatic mass in the paratracheal and supraclavicular region with a normally
located thyroid gland
