Putaminal rim sign

The putaminal rim sign, also known as the putaminal slit sign, is a relatively specific sign of multiple system atrophy - parkinsonism (MSA-P), and refers to a linear region of high signal surrounding the lateral aspect of the putamen at 1.5 T MRI on T2 weighted images or ADC map. Importantly this appearance can be seen in normal individuals at 3 T 1
