Alexia without agraphia

This typical case of alexia without agraphia, caused by an astrocytoma, is the first recorded case in the literature of alexia without agraphia with a right homonymous hemianopia caused by a tumor. This case differs from previously reported cases of the syndrome by its fluctuating clinical course and its slow progression. All but one of previously reported cases had been of vascular or surgical etiology. This course and the associated radiographic findings should differentiate the neoplastic from the vascular etiology of this most fascinating syndrome.
