gerstmann’s syndrome in non- dominant hemisphere: a case report

Gerstmann rsquo;s syndrome is caused by a left (dominant) inferior parietal lesion, particularly involving the angular gyrus or subjacent white matter of the left hemisphere. we describe case of an 80 year old right handed man admitted to our hospital with history of sudden onset of blurred vision. at first in neurological examination, he had left hemonymus hemianopia and characteristic features of gerstmann rsquo;s syndrome. in the requested paraclinical test, computed tomography (ct) scan showed hypo dense area in the right occipital lobe with expansion to parietal and temporal lobe. gerstmann rsquo;s syndrome is characterized by four symptoms: aghraphia, acalculia, finger agnosia and rightleft disorientation. one or more of these manifestations may be associated with word blindness (alexia) and hemonymus hemianopia or lower quadrantanopia.in our case, gerstmann rsquo;s syndrome is caused by a lesion in non dominant hemisphere, which madethis case worth for reporting.
