Ectopic Thyroid Tissue

Ectopic thyroid tissue is a rare entity and when discovered it is typically along the pathway of embryologic migration of the thyroid. We present a case of incidental finding of ectopic thyroid tissue within mediastinum in a 61-year-old female patient with a history of total thyroidectomy for thyroiditis and nodules. The patient presented to emergency room with cough and right chest pain and underwent a chest computed tomographic angiogram (CTA) to exclude pulmonary embolism as part of chest pain workup. One right paratracheal mediastinal soft tissue nodule was visualized on the images of CTA. This right paratracheal soft tissue mass was found to be ectopic benign thyroid tissue by histological analysis of the biopsied tissue samples. The function of this ectopic thyroid tissue was characterized by I-123 radioiodine uptake and single photon emission computed tomography/computed tomography (SPECT/CT) imaging. This case illustrates that ectopic thyroid tissue should be included for differential diagnosis of a hyperdense soft tissue mass located within mediastinum. I-123 SPECT/CT is useful for guiding tissue biopsy of ectopic thyroid tissue distant from orthotopic thyroid gland and functional and anatomic characterization of mediastinal ectopic thyroid tissue for surgical resection when it is medically necessary.

Clinical Behavior

The findings at radiography, computed tomography and angiography and the clinical course of 30 cases of angiosarcoma were reviewed. The variety of primary sites results in a multitude of findings but the most common finding was that of a hypervascular soft tissue mass seen on CT and angiography. Additional findings of well demarcated cortical defects in long bones were also frequently noted. The general clinical behavior of these aggressive malignant tumors was also reviewed and it was noted that they had a deceptively benign presentation.

Measurements of crown-heel length, head circumference, and birth weight were made on a large number of newborn infants. Birth weight by itself was frequently not a valid measure of fetal growth impairment. By including measurements of body length and head size along with birth weight, four distinct patterns of fetal growth impairment were identified. The four patterns included infants who had abnormally short body lengths for dates, infants who had evidence of disproportionate growth between body length and head circumference, infants who accumulated excessive amounts of soft-tissue mass, and infants who accumulated too little soft-tissue mass. Criteria for diagnosing each pattern were obtained prospectively and have been presented with allowances made for the effects of race, sex, fetal age, and parity on each pattern. The separate identification of the four patterns provided a more precise description of fetal growth impairment than could be obtained from birth weight and calculated gestational age.
