Additional representative MRI data before treatment. DWI (a), ADC-map (b), time-of-flight angiography (c) and SWI data (d) that resulted in a consensus diagnosis of “probable CLIPPERS.” Features of CLIPPERS pathophysiology: there was no restricted diffusion such as an insult or tumor, no appreciable vascular stenosis or malformations (we noted unremarkable asymmetry of vertebral arteries); deep curve vessel fragments (prominent veins) were seen on DWI and SWI (arrows).
