説明
We report route finding defect in 2 patients with subcortical hemorrhage. In one patient, the hemorrhage involved in the right medial parieto-ocipital lobe including the retrosplenial region. In the patient with hemorrhage in the right posterior inferior temporal lobe, SPECT showed hypoperfusion in that region extending to the right parieto-occipital lobe. Both patients displayed topographical disturbance, mild visuoconstructive disability and transient metamorphopsia during their acute phase of illness. They could recognize landmarks (streets and familiar houses, etc.), but failed to recognize the relative positions of landmarks, indicating that their topographical distrubance was a route finding defect due to perceptual distrubance and or memory disturbance of the relative positions of landmarks.<BE><BR>We presumed that their defective route finding may have been caused by the medial parieto-occipital and retrosplenial lesions.<BR>A careful differentiation between route finding defect (disturbance of recognition or memory for the relative positions of landmarks) and agnosis for streets and houses (disturbance in the recognition of landmarks) should be made in the evaluation of topographical disturbances.
