From the case:
Prominent perivascular space
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/47910/annotated_viewer_json?_c=1669321355\u0026lang=us"}
Rounded hypoattenuating focus within the inferior portion of the right lentiform nucleus most consistent with a prominent perivascular space.

MRI confirms the right inferior lentiform nucleus hypoattenuating focus on CT to follow CSF intensity consistent with a prominent perivascular space rather than a lacunar infarct.
Case Discussion
Typical CT and MRI appearance of a prominent perivascular space inferiorly within the basal ganglia which should not be mistaken for a lacunar infarct.
