[A case of learning-disabled child with a white matter lesion in the left parietal lobe].

We reported a learning-disabled boy, 7-year-old and right handedness, who was similar to developmental Gerstmann syndrome. Dyscalcuria, right-left disorientation, dysgraphia and finger agnosia were correlated with his sequential disorder which was clearly presented by Kaufman Assessment Battery for Children. In this case, a small infarcted lesion was found in the white matter near the left semioval center on MRI. Hypoperfusion of left parietal lobe was also detected by SPECT. The hemisphere dominant in language was assumed to be on the left side by dichotic listening test. We suggested that left parietal lesion was associated with his higher cortical dysfunction.
