Bilateral opercular syndrome and crossed aphemia due to a right insular lesion: a clinicopathological study

Brain Lang. 1988 Jul;34(2):253-61. doi: 10.1016/0093-934x(88)90137-x.


A right-handed male patient suddenly noted lower bilateral facial and lingual palsy, and inability to masticate and swallow, but with preserved automatic functions. He was mute, communicating only through writing, but verbal comprehension was normal (aphemia). On anatomopathological examination, an ischemic infarction of the entire right insula, with mild extension to the fronto-temporoparietal operculum was observed. The left hemisphere was normal. The clinical findings suggest a bilateral opercular syndrome due to a right hemisphere lesion and a crossed aphemia.
