In our case, a radioiodine avid left adrenal gland metastasis was suspected on iodine 131 WBS and confirmed by additional I-131 SPECT/CT imaging.
The thymus would suffer less damage, and some thymic tissues may remain compared with the thyroid after radioiodine therapy.
Of these, 555 were hypothyroid, 98 were hyperthyroid and treated with antithyroid drugs, 75 underwent radioiodine treatment for Graves' disease or Plummer adenoma, 100 underwent thyroid surgery for compressive symptoms or malignancy, 527 had nodules smaller than 5 mm, were lost at follow-up, or had less than 3 visits, 100 had chronic autoimmune thyroiditis in euthyroidism, 25 were treated with ethanol ablation for cystic nodules, and 43 underwent suppressive therapy with levothyroxine for nodular goiter.
These studies evaluated whether rates of successful ablation would be similar among patients receiving recombinant human thyrotropin (rhTSH), patients undergoing thyroid hormone withdrawal (THW) and among patients receiving low or high amount of radioiodine.
In a retrospective study of 621 patients (25), patients treated with radioiodine had increased risk of spine and forearm fractures, especially in age group 50 years or older.

In rare cases, cats may become hypothyroid and require thyroxine supplementation or may require a follow-up dose of radioiodine to successfully restore normal thyroxine levels, but these are highly unlikely to occur.
