He never showed any clinical evidence of the radiation exposure and by one year he had recovered from the acute findings. His subsequent medica] history has been largely negative up to the present thyroid findings. He has had no retardation of growth and development and has always appeared to be euthyroid, The first indication of thyroid abnormality was noted in 1966 when the gland was found to be slightly enlarged with a soft, l cm. diameter prominence in the lower right lobe with several small nodules noted on the left side also. His PBI and cholesterol levels _ were normal at that time. During the next two years continued enlargement of the nodules of the thyroid were noted and the T-4 level had reduced 2.6 ug.%. Examination this past March (1969) revealed that the mass in the lower right lobe was about 2-3 cm. in diameter with a cluster of smaller nodules in the left side believed to be attached to the trachea. The T-4 level was again 2.6 ng.%. However, he appeared to be euthyroid. The patient had two brothers who had benign nodules removed a year ago, and his mother had a malignant lesion removed several years ago from the thyroid, PHYSICAL EXAMINATION: The patient was alert, healthy, and appeared to be euthyroid, Except for mild fungus infection of the skin the main findings were related to the thyroid gland. A soft prominence, 2-3 cm, in diameter, was noted in the right lower pole of the thyroid. Several lesser nodularities appeared to be present on the left side. No associated lymphadenopathy was detected. Thyroid studies revealed: PBI 4.3 ug.%, total todines 4.6 g.%, Ltodoproteins 1.6 yg.%, and T-4 3.2 px.%; BMR +3%; cholesterol 142, esters 107 mg.%. Thyroid scan showed a muitinodular thyroid with rather marked enlargement of the right lower lobe which contained mainly nonfunctioning tissue. Iodine uptake was normal but response to TSH stimulation was poor. Hemogram and blood chemistry findings were generally negative. X-ray of the chest was normal. Thyroid autoantibodies showed less then 1-16 dilution reaction. LABORATORY AND X-RAY FINDINGS; ONL 720A - 80 - a Bo Not Write In Binding Margin HISTORY OF PRESENT ILLNESS: RannF825 er" UPTON, NEW YORK
