Case contributed by Dr Andrew Dixon

Presentation

Confusion.

Patient Data

Age: 75
Gender: Male
CT

Rounded hypoattenuating focus within the inferior portion of the right lentiform nucleus most consistent with a prominent perivascular space. 

MRI

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.
