- •
We previously reported two PML cases showing low-signal-intensity rim along deep layers of the cerebral cortex on SWI.
- •
This finding could be seen in infarct and encephalitis, indicating it is not a specific finding to PML.
- •
Low-signal-intensity rim appeared to be associated with hyperintense cortical signal on T1-weighted images.
