Dilated perivascular space displays CSF signal
Case Discussion
Typical enlarged VR space - location inferior to the basal ganglia adjacent ot the terminal ICA with fluid having identical characteristics to CSF (it is a CSF-filled space). In this case we can actually see the vessel (penetrating barnch of the terminal ICA) passing through the space. It should not be confused with a cystic tumor or choroidal fissure cyst (in the choroidal fissure). This is best sorted out on the coronal projection.
