Table 3 Radiological site of lesions of 36 cases of ischemic stroke with aphasia

From: A hospital-based study of post-stroke aphasia: frequency, risk factors, and topographic representation

Types of aphasia Number of cases (%) Site of each lesion
Global aphasia 18 (50%) 12 cases total left MCA infarction
1 case total right MCA infarction
2 cases left frontal infarctions, involves the cortex and the subcortical WM, (MCA territory)
2 cases left parietal infarction, involves the cortex and the subcortical WM, (MCA territory)
1 case left parietal-occipital infarction
Broca’s (motor aphasia) 10 (27.8%) 3 cases left frontal operculum and the anterior insula
1 case right frontoparietal operculum and the insula (MCA territory)
3 cases left frontoparietal infarction, involves the cortex and the subcortical WM, with extension to the premotor, motor, and sensory areas at the lateral surface (MCA territory)
3 case left basal ganglionic infarction (putamen and lenticulocapsular region—MCA territory, lateral lenticulostriate).
Wernicke’s (sensory aphasia) 4 (11.1%) 2 cases left temporoparietal infarction, involves the cortex and the subcortical WM, (MCA territory)
1 case left temporal infarction, involves the cortex and the subcortical WM, (MCA territory).
1 case left basal ganglionic infarction, lentiform nucleus (MCA territory, lateral lenticulostriate)
Conductive aphasia 3 (8.3%) 3 cases diffuse small vessels ischemia (periventricular and deep WM)
Nominal aphasia 1 (2.8%) Left angular gyrus infarction (MCA territory)
  1. MCA middle cerebral artery, WM white matter
