A 6-year-old boy presented with neck swelling and global developmental delay since birth. A small swelling was noted in the posterior part of the tongue in the region of the foramen caecum. Thyroid stimulating hormone was grossly elevated (53 µU/ml). Pertechnatate radionuclide scintigraphy was performed for evaluation of the neck mass (Fig. 1). This revealed the absence of normal thyroid gland in the thyroid bed, but at three ectopic locations (region of the foramen caecum, suprahyoid and in the region of the cricoid cartilage) along the path of the thyroglossal tract (triple ectopia of thyroid gland). There have been eight reported cases of dual ectopia, but this appears to be the first case of triple ectopia [1].
