Patient Data

Age: 40
Gender: Male

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.
