title: Giant cerebral lacuna due to dilatation of the perivascular space: a case report.
abstract: The case of an asymptomatic giant cerebral lacuna situated in the left subputamenal region is reported. This lacuna was due to a dilatation of the perivascular space surrounding the lenticulostriate arteries at their entrance into the lenticular nucleus. This giant cavity was asymptomatic; however, the patient suffered from an atheromatous polyarteriopathy involving not only the arteries of the lower limbs and the coronary arteries but also both internal carotid arteries.
