Amiodarone Hepatotoxicity

Imaging findings

CT of the upper abdomen/chest demonstrates a diffuse, markedly increased attenuation of the liver parenchyma (extremely bright liver) and thyroid, characteristic of amiodarone deposition.

Key takeaways

Amiodarone is an iodine-rich antiarrhythmic medication that accumulates in the liver and thyroid, causing increased CT attenuation (hyperdensity). It can be associated with hepatotoxicity and thyroid dysfunction.
