ABSTRACT A 4 year-old girl was referred for CT of her neck for suspected submental lymphadenopathy and was found to have an incidental low-attenuation thyroid mass. Subsequent thyroid ultrasound showed a heterogeneous thyroid mass with punctate areas of increased echogenicity. Cytologic examination was consistent with ectopic intrathyroidal thymic nodule. We review the presentation of ectopic thymic tissue, especially in the thyroid gland. (c) 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 41:319320, 2013

    ABSTRACT: Intrathyroidal thymic tissue is rare and may be confused with a malignant thyroid nodule because of hyperechoic dots mimicking calcifications. We report the case of a thyroid nodule with malignant ultrasonographic findings in a 4-year-old child, which was confirmed cytologically as ectopic thymic tissue. The sonographic findings of ectopic thymus were similar to those of the thymus; therefore, clinicians should be familiar with ultrasonography findings of normal thymic tissue.

    ABSTRACT: Ectopic intrathyroidal thymic tissue can form a mass lesion within the thyroid gland and has rarely been reported in children. We report a case of intrathyroidal thymus accompanied by an intrathyroidal parathyroid gland in a 29-year-old woman who visited our hospital due to right neck mass diagnosed as metastatic papillary carcinoma by aspiration cytology in an outside hospital. She had a history of right thyroidectomy due to papillary thyroid carcinoma three years ago. Ultrasonographic examination of the left thyroid gland showed a well-defined hyperechoic nodule, which did not show change in size compared with the previous study. She underwent complete thyroidectomy with right neck dissection. Grossly, the left thyroid had a well demarcated pale yellow nodule measuring 0.9 cm in diameter. On microscopic examination, the nodule was composed of mature fat tissue, ectopic thymic tissue with Hassall's corpuscles, and an intrathyroidal parathyroid gland. This is an exceedingly rare case of ectopic intrathyroidal thymus with intrathyroidal parathyroid gland, in an adult.
