121 stroke patients with the dominant hemispheric lesions were classified by the Minnesota classification of aphasia and investigated with CCT.1) Euphasics (n=10) and aphasics, minimal (n=6) : The small confined lesions to the basal ganglia and the internal capsule were noted.2) Dysarthria (n=10) : The lesions wers small, bilateral and scattered.3) Group 1 (n=30) : The low density areas were found in the basal ganglia, the internal capsule, F3, T1, the supramarginal gyrus etc. No predilection area was found.4) Group 3 (n=6) : The low density areas were definitely found in F3 (Broca's area) and distributed to the surrounding cortical and deeper structures.5) Group 4 (n=6) : The lesions in CCT were small and limited compared with the severity of language disturbance.6) Group 5 (n=15) : The wide spread low density areas including F3, T1, the insula, the supramarginal, the angular gyrus and the deeper structures were recognized.7) Minor A (n=18) : The low density areas of T1 (Wernicke's area) and its surrounding stracture were present.8) Minor B (n=6) : The small low density areas were found in the basal ganglia and/or the internal capsule or the frontal operculum.9) Combined syndromes of Minor A and Group 3 (n=3) : Cases of this group had the syndromes of severely affected oral language comparing written one. The site of the lesions in CT was combination of F3 and T1.10) Others (n=11) : No common site and spread of the lesions in CCT were found.
