Subcortical crossed aphasia: a case report.

A 74-year-old, right-handed woman suffered acute aphasia and left hemiplegia secondary to a cerebral infarction in the right cerebral hemisphere. The lesion was located deep in the parietal lobe and extended to the posterior limb of the internal capsule and the head of the caudate nucleus. The patient's aphasia was characterized by severe impairment in auditory and visual comprehension and auditory retention span, as well as by anomia, agraphia, and dyscalculia. She showed rapid recovery from her aphasia, with residual deficits in writing, naming, calculation, and memory.
