ABSTRACT
A 6-year-old boy developed hemorrhage in the left temporal lobe and subsequently underwent left temporal lobectomy. Afterwards, he was completely unable to learn to read or write. Psychological tests showed impairment in verbal learning and memory, with right ear and right visual field superiority in verbal perception. A Wada test showed no aphasia after right carotid injection. We conclude that damage to the speech-dominant temporal lobe resulted in the inability to learn to read or write. Despite the lesion, speech remained strongly lateralized to the left hemisphere, accounting for the right-sided advantage in verbal perception. Some patients with developmental dyslexia may have dysfunction of a strongly dominant left hemisphere rather than a delay or incompleteness of language lateralization.
