Hemianesthesia and aphasia. An anatomical and behavioral study

Arch Neurol. 1989 Jul;46(7):816-9. doi: 10.1001/archneur.1989.00520430112026.


A 61-year-old right-handed man with a history of lacunar cerebrovascular disease and hypertension had the sudden onset of right-sided numbness and difficulty speaking. Neurologic evaluation revealed a dense right hemianesthesia that included the face, trunk, arm, and leg. Neuropsychological examination documented a conduction aphasia, which resolved nearly completely several months later. Computed tomographic and magnetic resonance imaging studies showed a lesion in the left hemisphere that involved the posterior insula and disrupted thalamocortical connections but entirely spared the thalamus proper. We suggest that the combination of hemianesthesia and aphasia indicates a white matter lesion subjacent to inferior parietal and posterior temporal cortices.
