      The basal ganglia and thalami are paired deep grey matter structures with extensive metabolic activity that renders them susceptible to injury by various diseases. Most pathological processes lead to bilateral lesions, which may be symmetric or asymmetric, frequently showing characteristic patterns on imaging studies.

      Conclusions—Lacunar infarcts in the basal ganglia caused marginally severer strokes and were 3 times more likely to have a potential embolic source than those in the centrum semiovale, but the overall rate of carotid or known cardiac embolic sources (11%) was low. We found no evidence that other risk factors differed with location, size, or ...

The resultant lesions are deep small infarcts, most often involving the basal ganglia, pons, thalami and cerebral white matter.
