Abstract:
Amiodarone is a triiodinated antiarrhythmic drug that accumulates in alveolar macrophages. Its use is limited by its high rate of associated pulmonary toxicity, estimated at 5-7%. Radiologic findings for pulmonary toxicity caused by amiodarone are unspecific and varied. The most common finding is subpleural reticular-type interstitial thickening, predominately in the bases of the lungs. However, the presence of parenchymal nodules is an uncommon presentation. We report the case of a woman treated with amiodarone that presented multiple nodular lesions at plain-film radiography and high-resolution CT that were compatible with pulmonary toxicity caused by amiodarone at pathologic examination.
