A patient is presented in whom right temporal AVM excision led to improved cognitive function. Neuropsychological assessment showed a significant postoperative improvement in Performance IQ (p = < 0.05), Full Scale IQ (p = < 0.05), and clinically in visual memory (p = < 0.10). Reversal of vascular steal may lead to increases in cognitive function. We recommend that patients undergoing AVM excision have a complete neuropsychological evaluation.
