He was diagnosed with hyperthyroidism 8 months ago and he was treated with antithyroid drugs for 6 months, but he stopped taking the medicine 2 months ago. Abdominal computed tomography revealed typical findings of SMA syndrome. His symptoms subsided shortly after treatment of hyperthyroidism including antithyroid drugs, beta blocker therapy. Then he took radio-iodine treatment. He has taken synthyroid as hypothyroidism after radio-iodine therapy and maintained euthyroid state.
