Hemiagenesis of the thyroid

This 18 yr. old female patient presented with symptoms of hypothyroidism. On sonography of the thyroid, we observed:  2) normal or slightly enlarged left lobe and isthmus of thyroid c) mild to moderate augmentation of vascularity of the left lobe on color doppler imaging. These ultrasound images favor a diagnosis of congenital absence of the right lobe or hemiagenesis of the right lobe with Hashimoto's thyroiditis. This condition is found typically in females with left lobe usually absent.
