title: Hybrid SPECT/CT evaluation of dual ectopia of thyroid in the absence of orthotopic thyroid gland.
abstract: Ectopic thyroid tissue (ETT) refers to all cases in which the thyroid gland is present at a location other than its usual site. The prevalence of ETT is approximately 1 per 100,000 to 300,000 persons and is reported to occur in 1 of 4000 to 8000 patients with thyroid disease. Multiple ectopia of the thyroid is extremely rare, with fewer than 35 cases published in literature to date. We report a 4-year-old girl with euthyroid and dual ectopia of thyroid without orthotopic thyroid gland. The role of hybrid SPECT/CT in the localization of the sites of ETT is also highlighted.
