- Figure 1
Chest computed tomography axial views demonstrated increased attenuation in the liver (A, arrow) and left pleural base (B, arrow). Evaluation of the right lung base revealed ground-glass opacities (C, arrow) and honeycombing (D, arrow). These findings were consistent with amiodarone pulmonary toxicity.
- Figure 2
In A, repeat chest computed tomography demonstrated increased liver attenuation (arrow); in B, it showed persistent ground-glass opacities (white arrow), increased pulmonary attenuation (black arrowhead), and worsening pleural effusions (black arrows). These findings supported the diagnosis of amiodarone pulmonary toxicity.
