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