Summary
Two new cases of alexia without agraphia are presented. Pertinent clinical findings, anatomy, pathophysiology and differential diagnoses are reviewed. The importance of carefully examining the inferior portion of the left side of the splenium of the corpus callosum on CT and/or MR scans in patients who present with this clinical syndrome is stressed.
