Amiodarone Toxicity

68-year-old male presented with atrial fibrillation during an acute episode of diverticulitis. He was started on amiodarone with good response. He presents 9 months later with dyspnea. CT scan in the axial plane through the lung bases show reticular changes characterised by irregular thickening of the interlobular septa, mild heterogeneous ground glass changes mosaic attenuation centrilobular nodules and bronchiolectasis suggesting a combination of small airway disease and an alveolitis with early fibrotic changes . These findings are consistent with amiodarone toxicity

CTscan in the axial plane through the lung bases show reticular changes characterised by irregular thickening of the interlobular septa (a), centrilobular nodules, (b)mild heterogeneous ground glass changes (c) mosaic attenuation (d, teal ring) and small airway wall thickening and bronchiolectasis (d yellow ring) suggesting a combination of small airway disease and an alveolitis with early fibrotic changes. These findings are consistent with amiodarone toxicity.
