The most common method for evaluation of language function at the bedside is confrontation naming task. This is most often done with visually presented objects such as the naming page of the NIHSS questionnaire. Visual agnosia caused by a lesion in visual pathways might lead to mis-localization and delay in diagnosis and care for a patient with acute stroke presenting with visual disturbances.

We present a 69-year-old right-handed male who presented with speech difficulty and was transferred to us for consideration of intravascular intervention for his left ICA occlusion.

After further clinical assessment of his speech, we noted that he had difficulty with naming of visually presented items specially when they needed more visual processing suggestive of visual agnosia although his spontaneous speech was fluent. He also had alexia without agraphia and right sided homonymous hemianopia. Further evaluation of his CTA showed a left P2 occlusion and later his MRI confirmed a left PCA infarct.

Using verbal and tactile stimulation for naming can distinguish difficulty with naming caused by language network dysfunction from visual agnosia. Also testing for writing should be done to clarify the nature of language deficit and distinguish visual processing deficit from a primary language deficit.
