Sub-insular bright spots

Sub-insular bright spots are actually no more than multiple small perivascular spaces located between the insular cortex and the claustrum (within the extreme capsule), following the perforating vessels that arise from the branches of the MCA.

They are extremely frequent (80-100% of patients) 1 and are increasingly noted with better MRI imaging. They are round or elliptical (66%) or linear in shape 1.
