Magnetic resonance imaging of hydroxychloroquine-induced cardiomyopathy

Magnetic resonance imaging (MRI) using black blood imaging in a 76-year-old female with longstanding rheumatoid arthritis treated with hydroxychloroquine (panel A) shows a thickened left ventricle (arrow) and a small pericardial effusion (arrowhead). The delayed T1-weighted sequence following gadolinium (panel B) shows mid-ventricular delayed enhancement (arrows). These findings are consistent with a nonischemic cardiomyopathy. Cardiac catheterization showed restrictive physiology.
