Lacunar infarctions are small, deep cerebral infarctions believed to be caused by intrinsic small-vessel disease secondary to lipohyalinosis and fibrinoid necrosis; they are most frequently observed in patients with hypertension or diabetes mellitus. Common sites for these lesions include the basal ganglia, internal capsule, thalamus, brainstem, and cerebellum. MRI findings in these lesions follow the same pattern observed in thromboembolic infarction.
