ABSTRACT
Amiodarone-induced thyrotoxicosis is a common complication of long-term amiodarone treatment. In a patient with amiodarone-induced lung toxicity and amiodarone-induced thyrotoxicosis type 2 (AIT2), a "white thyroid" was incidentally observed on an unenhanced chest computed tomography (CT) scan. This "white thyroid" resembled a thyroid image on a contrast-enhanced CT scan. Therefore, the thyroid density was prospectively evaluated on unenhanced CT scans in cases of AIT2, in euthyroid patients on amiodarone (AEuth), and in unexposed controls. The aim was to test the hypothesis of a higher thyroid density in AIT2 compared to AEuth. The thyroid density, as measured in Hounsfield Units on unenhanced CT scans, is higher in AIT2 compared to AEuth and much higher than in controls. The causality of this association and its potential diagnostic use require further study.
