title: T4-thyroid storm after CT-scan with iodinated contrast medium.
abstract: A 62-year-old woman had thyroid storm 5 h after a CT examination (contrast enhancement with 65% meglumine amidotrizoate, Angiografin). At the time of admission to our hospital, serum T4 and serum free T4 levels were markedly elevated (29 micrograms/dl and 9.6 ng/dl, respectively); serum T3 and serum free T3 levels were within normal limits (144 ng/dl and 5.9 pg/ml, respectively). These findings suggest that thyroid storm can occur with excess T4 only (T4-thyroid storm), and that T4-thyroid storm can be caused by administration of iodinated contrast medium.
