Subjects with a lacunar infarction due to small penetrating artery occlusion are often considered "minor" stroke by both laymen and many clinicians.
Cranial magnetic resonance imaging (MRI) performed 10 days after the onset showed an infarction in the left ventromedial part of the upper mesencephalon and old multiple chronic lacunar infarctions in the deep white matter of the cerebral hemispheres (Figure 1C) Over the next week her hemiparesis resolved completely and her diplopia was getting better.
8 percent of the participants had the silent lacunar infarctions, small areas of damage to the brain seen on MRI that never caused obvious symptoms.
