The resulting deficit will be "alexia without agraphia" - i.e, the patient can write but cannot read (even what they have just written).

It is also known as "Dejerine syndrome" (after Joseph Jules Dejerine, who described it in 1892^[1]), but it should not be confused with medial medullary syndrome, which shares the same eponym.

It can be associated with a lesion of the occipital lobe and splenium of the corpus callosum.^[2]
