Physical examination revealed a palpable thyroid with a 2 cm in length in its isthmus and large right lobe. Kyphotic patient was tachycardic. Other systems were within normal limits. Chest x-ray performed wide upper mediastinum with calcified nodule approximately 3.5 cm in dimension in the apex of the left lung.
