A case of dual ectopic thyroid accompanied by positive antithyroid antibodies.
Ectopic thyroid tissue is an uncommon congenital aberration that is seldom present at two different sites simultaneously. The patient was a 32-year-old woman with dual ectopic thyroid accompanied by positive antithyroid antibodies. The simultaneous occurrence of dual ectopic thyroid and positive antithyroid antibodies has been documented in only two cases: the case discussed here and one previous case. The cervical ectopic thyroid was followed up by ultrasound, which showed an increase in the size of the lesion and an internal echo texture that became slightly heterogeneous after the patient had her second child. We speculated that these changes resulted from the changes in hormone demand brought on by pregnancy and parturition.
