The putaminal rim sign, also known as the putaminal slit sign, is said to be 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.
Unfortunately, this appearance can be seen in normal individuals when imaged with 3 T MRI 1.

Neurodegenerative diseases are legion and their classification just as protean. A useful approach is to divide them according to underlying pathological process, although even using this schema, there is much overlap and thus resulting confusion.
