Crossed aphasia: analysis of a case with special reference to the nature of the lesion.

We report a case of crossed aphasia in a strongly right-handed woman due to a parieto-occipital tumor in the right hemisphere, documented by CT and MR images. Neuropsychological assessment was conducted on four different occasions: results revealed an uncommon feature in our case, because of the nature of the lesion and the evolution of the clinical picture. These findings are discussed in relation to the literature.
