Aphasia Following Right Striato‐insular Infarction in a Left‐handed Child: a Clinico‐radiological Study

The case of six-year-old girl with non-fluent aphasia following a subcortical right-hemispheric cerebrovascular accident is reported. Examination by computerised tomographic scan revealed a right paraventricular area of diminished density involving the internal capsule, lenticular nucleus and the insula. The speech disturbance was followed by typical right-hemispheric signs and by left-channel extinction in dichotic listening tests. The aphasia cleared in two weeks, paralleled by an improvement in left-channel performance, suggesting that language recovery was dependent on right-hemispheric structures.
