Failure to demonstrate selective deficit in the native language following surgery to the left perisylvian area

Gomez-Tortosa, Martin, Gaviria, Charbel, and Ausman (1995) reported a case of a Spanish-English bilingual with a left perisylvian arteriovenous malformation that was surgically resected. They claimed that, following the surgery, the patient showed a selective deficit in her native Spanish. Statistical analysis of the data in the report provides no support for this claim.
