Key result
Amiodarone-related interstitial lung disease shows variable presentations and recurs rapidly after brief re-exposure.
Why the study?
Amiodarone is commonly used but has potential pulmonary toxicity, prompting a need to demonstrate variable features of amiodarone-related ILD and highlight the importance of cessation and avoiding re-exposure.
What are the variable radiographic and histologic presentations of amiodarone-related interstitial lung disease and the consequences of re-exposure?

What are the variable radiographic and histologic presentations of amiodarone-related interstitial lung disease and the consequences of re-exposure?
Amiodarone can cause severe interstitial lung disease with highly variable manifestations, underscoring the necessity of immediate discontinuation and avoidance of re-exposure.

Amiodarone re-exposure may trigger rapid ILD recurrence; case reports leave open variable presentations for larger confirmation.
Amiodarone is a commonly used antiarrhythmic agent but exhibits potential pulmonary toxicity. In this case series, we describe the clinical, radiographic, and histologic manifestations of three patients who developed interstitial lung disease (ILD) following amiodarone treatment for variable lengths of time with different dosages. The presentations on computed tomographic images and in pulmonary pathology differed among the three patients. All three had immediate discontinuation of amiodarone and received treatment with systemic corticosteroids. One patient eventually died from ventilator-associated pneumonia after an initial improvement. The other two patients recovered well but later experienced ILD recurrence following brief re-exposure to amiodarone. Through this case series, we aim to demonstrate the variable features of amiodarone-related ILD, and highlight the importance of timely amiodarone cessation and avoiding re-exposure to prevent the progression and recurrence of ILD.

Tsai et al. (2023) conducted a case report in Amiodarone-related interstitial lung disease (n=3). Amiodarone was evaluated on Clinical, radiographic, and histologic manifestations of interstitial lung disease. Amiodarone-related interstitial lung disease presented with variable radiographic and histologic features in three patients, with rapid recurrence observed upon brief re-exposure.
