Iodide-induced Hyperthyroidism Within Four Hours of Iodide Load: A Case Report and Review

The recommended amount of iodide consumption for the majority of adults is approximately 150 mcg per day. During a computed tomography scan, patients can receive 14 to 35 million mcg of iodinated contrast. A 46-year-old African female with no known prior thyroid disease presented with dyspnea and tachycardia. She underwent computed tomography angiogram of the chest to rule out pulmonary embolism. She had evidence of hyperthyroidism four hours after receiving iodinated contrast. We presumed that her hyperthyroidism was a consequence of the Jod-Basedow phenomenon due to an underlying multinodular goiter that was later discovered.
