Abstract

|
Crossed aphasia cases are uncommon and rarely seen. It means that aphasia symptom caused by right hemispheric lesion in right-handed patient. The pathophysiologic mechanism of this phenomenon is not clearly elucidated. But, several pathophysiologic mechanism including mirror image hypothesis and anomalous dominance hypothesis are suggested in previous literature. We describe a case of dissociated crossed aphasia and anarthria caused by right hemispheric lesion in right-handed patient. Aphasia study using Modified Western Aphasia Battery interpretated motor-dominant aphasia in spite of major right hemispheric lesion including middle and anterior cerebral artery area. This case supported anomalous dominance hypothesis and demonstrated that variety of symptoms an aphasia type distribution in crossed aphasia.
