Evidence of dual ectopic thyroid tissue by thyroid scintigraphy in 6 cases in our study.
Thyroid scintigraphy was performed as described in Materials and Methods. Dual ectopic thyroid tissue were identified in 6 cases, who displayed 2 focal areas of abnormal radiotracer uptakes in the sublingual and subhyoid regions in thyroid scintigraphies. No evidence of radiotracer uptakes in the regions of orthotopic thyroid was found. Anterior and lateral views of patient 1 and patient 2 were presented. Anterior views of the other 4 patients were shown as well.

Clinical parameter distribution patterns in all reported cases with dual ectopic thyroid tissue.
Altogether, clinical data of 42 cases with dual ectopic thyroid tissue were compiled. And distribution patterns of age (A), sex (B), thyroid function (C) and ectopic thyroid tissue location (D) were demonstrated in pie charts.
