title: Selective deficit of one language in a bilingual patient following surgery in the left perisylvian area.
abstract: We report on a right-handed bilingual patient with a left perisylvian arteriovenous malformation that caused a mild naming deficit evident only on formal language testing in both languages. Sodium amytal injected in the left carotid artery (Wada test) before surgery resulted in speech arrest for both languages. Following surgery for removal of the lesion she developed additional deficits in her native language without alteration in her second language. Selective impairment in one language after surgery demonstrates that each language has different anatomical representation within the perisylvian dominant area.
