Lexical agraphia reflects a dysfunction of the lexical spelling system and is characterized by better spelling of non worda and regular words than irregular words. All previously reported casea with documented focal lesions had involvement of temporo-parieto-occipital regions. We now report a case of lexical agraphia following a discrete lesion of the left precentral gyrus. Our caae complements previous neuroanatomical accounts of agraphia and provides further support for the independence of neuronal systems that mediate spelling from those involved in spoken language and reading.
