Abstract
Conduction aphasia is a language disorder characterized by an impaired ability to repeat verbal material associated with phonological paraphasias but a relatively fluent spontaneous speech and preserved comprehension. It has been attributed to lesions of the arcuate fasciculus by disconnection between posterior temporal lobe and frontal lobe, however, this idea has been debated, because the integrity and function of the arcuate fasciculus does not seem to be essential in verbal repetition. We report a case of a 23 year old male, with conduction aphasia as a result of a recurrent anaplastic astrocytoma in parietal and temporo-occipital areas. We propose a reconceptualization of the aphasia, analyzing it in terms of clinical neuropsychological and neural networks between ipsilateral and contralateral posterior brain areas.
