[Spontaneous remission of an amiodarone-induced pulmonary lesion].

Amiodarone is an effective class-III antiarrhythmic agent. However, during long term therapy 1-10% of patients develop severe adverse pulmonary reactions, which are potentially life threatening. We report the case of a patient who developed dyspnoea and extensive pulmonary infiltrates compatible with amiodarone-associated interstitial lung disease following 6 months of treatment with amdiodarone (300 mg daily) for atrial flutter. On discontinuation of amiodarone treatment the infiltrates impressively resolved almost completely within 8 weeks, without administration of corticosteroids.
