Gerstmann's syndrome, assigned to a lesion of the dominant parietal lobe, is a neurological disorder characterized by acalculia, agraphia, right-left disorientation and finger agnosia. Some studies report that these symptoms are also shown in other brain lesions. We report two patients who presented with this tetrad of symptoms in initial assessment. Their Brain MRI images both showed lesion of left frontal lobe. Over time, these symptoms became better but some still remained in last assessment. Accordingly, we suggest that a left frontal lesion cause Gerstmann's syndrome.
