An eight-year-old rhesus monkey (Macaca mulatta) presented an ischemic attack in the subcortical region of the right temporal area, naturally acquired by a hypoglycemic shock, generating asphyxia and arterial hypotension at 6 months old.

MRI performed showed ischemia in the right parietal lobe (Fig 1), from the injury focus in the middle cerebral artery, in the cerebral branches (insular and opercular branches) (Fig 2). The loss of continuity in the nerve fibers can be seen through the tractography, corresponding to encephalomalacic changes (Fig 3)1,2.
