Aphasia in a dextral after right hemisphere injury is called crossed aphasia (CA). We are reporting a first case of transformation of motor aphasia to conduction aphasia after right hemisphere intracerebral hemorrhage (ICH) associated with arteriovenous malformation (AVM) with literature reviews.
A case of a man in his 30s with CA following right hemisphere ICH in the temporal-parietal lobe associated with AVM was reviewed. We analyzed his brain images, initial linguistic characteristics, and changes in aphasia for 8 weeks of follow-up.
The initial Paradise Korean Western Aphasia Battery Revised (PK-WAB-R) was evaluated as aphasia quotient (AQ) 72, 64%ile; post evaluation was evaluated AQ 95, 98.9%ile after 8 weeks. The post-test repetition score was the patient score range, which can be attributed to impairment in phonological short-term memory. The patient is diagnosed anomalous CA based on Alexander et al., and we could predict that the language ability originates from both hemispheres based on Nagaraja et al. Considering the appearance of Gerstmann syndrome at the beginning of the onset, we could expect that the function of the dominant parietal lobe is partially crossed as well.
Changes in aphasia were reported throughout the initial stage to the end of speech therapy. It is also important to note that literature review of Korean studies was analyzed in this study. It will be necessary to conduct a cognitive test in the early stage of onset to understand the language problems of crossed conduction aphasia to know the characteristics of the cognitive process.
