We examined a patient who exhibited Gerstmann's syndrome (left-right
disorientation, finger agnosia, dyscalculia, and dysgraphia) in association
with a perioperative stroke in the right parietal lobe. This is the first
description of the Gerstmann tetrad occurring in the setting of discrete
right hemisphere pathologic findings. A well-localized vascular lesion was
demonstrated by computed tomography, magnetic resonance imaging, and
single-photon emission computed tomographic studies. The patient had
clinical evidence of reversed functional cerebral dominance and radiologic
evidence of reversed anatomic cerebral asymmetries.
