Dyslexia in a right-handed patient with a posterior lesion of the right cerebral hemisphere.
A 44-yr-old man was tested 17 months after he had a benign tumour in the lateral ventricle removed via a transverse surgical incision through the posterior temporal-parietal region of his right hemisphere. As a result of the surgical incision he suffered a number of visuo-spatial deficits, and test results strongly suggested he had speech lateralized in the left hemisphere. His speech and writing were normal but he suffered from a form of dyslexia. Most of the components of his disorder have previously been documented only in patients with left-hemispheric lesions.
