| Summary: | We report the case of a patient undergoing two surgeries in the right and left occipital lobes for resection of primary central nervous system tumor at different times. The first approach was performed in the left hemisphere, with the patient awake and, five months later, the second approach was performed in the right hemisphere, with the use of VEP for the study of the visual pathways. Both procedures were performed by the same surgical team, anesthesiologist and intraoperative monitoring neurophysiologist. Nevertheless, the outcomes were different, and the patient evolved with a left inferior temporal quadrantanopia after the second surgery, a deficit not detected by VEP.
