Lacunar infarction in the elderly

Lacunar infarction is a concept of pathology-CT-clinical integration. It is a common disease in the elderly, with a high incidence in the 60 to 70-year-old group. Fisher described it as: an ischemic micro-infarction (or softening) that occurs in deep perforating arteries (or other small arteries), and an irregular cavity formed after chronic healing. The diameter of the involved microarteries is about 200 micrometers; the pathological change is a cavity or infarction of 2 to 20 mm. The CT scan of the skull shows 2 to 20 mm (generally should not exceed 15 mm) of varying degrees of density reduction. More than 20 lacunar syndromes have been diagnosed.
