Abstract	We reported a patient in whom a change from aphemia to Broca's aphasia was observed after two separate infarctions in the territory of the left middle cerebral artery. The first stroke caused lesions restricted in the left precentral gyrus, and the patient had aphemia. The second stroke 7 years later caused additional lesions involving the frontoparietal operculum, the middle frontal gyrus, and insular cortex in the left hemisphere, and word finding difficulty, comprehension deficits, and disturbance in reading and writing were developed as well as articulation deficits, which is consistent with typical Broca's aphasia. Our experience suggested that the different lesion sites are attributable to the different aspects of language disturbance in Broca's aphasia.
