Brain mapping for lower-grade glioma around Wernicke's area.

Surgery of lesions around Wernicke's area is challenging for several reasons. The anatomical boundaries are not clearly defined, necessitating functional identification in addition to anatomical landmarks. There are potential complications secondary to injury of the surrounding structures. This challenge is more substantial when dealing with lower-grade gliomas in this region, as surgeons must balance the extent of resection with the risk of potential injury to the patient, especially considering that there may be other treatment options for the management of residual tumors. In this video, the authors present a case illustration, discussing surgical considerations and strategy. The video can be found here: https://stream.cadmore.media/r10.3171/2024.10.FOCVID24101.
