The patient is a 63 year old right handed woman with history of hypertension and non-insulin dependent diabetes mellitus, who complained of episodic right arm parasthesia and inability to read. On neurologic examination, she was an alert, oriented middle-aged woman. She had a fluent anomic aphasia (occasional word-finding difficulty and paraphasias, intact repetition). She could write a grammatically complex sentence, but was unable then to read it back. She had difficulty recognizing some letters of the alphabet, but if she could spell out the individual letters verbally, she had no difficulty in recognizing the word, i.e., alexia without agraphia. She had hemiachromatopsia (loss of color vision) in the right visual field, and a right homonymous superior quadrantanopsia. There was a very mild right pronator drift but otherwise normal motor exam, and a slight decrease in pinprick perception in the right hemibody. She had symmetric reflexes and flexor plantar responses.
