The presence of ischemic foci in the right lateral ventricle mostly suggests that the patient has atherosclerosis, which usually occurs in middle-aged and elderly people over 50 years old. It is a manifestation of cerebral ischemia and hypoxia, but no infarct foci have been formed yet, and the patient can have no clinical symptoms and signs, which mostly suggests that the patient has increased blood viscosity. Blood lipids, blood glucose and blood pressure should be checked, and if necessary, oral aspirin can be taken to antiplatelet aggregation and oral statins, such as simvastatin, resevastatin or atorvastatin to regulate lipids and stabilize plaques to prevent patients from progressing to cerebral infarction. If cerebral infarction develops, most patients may present with signs and symptoms, depending mainly on the site of lesion involvement and the size of the infarct site.
