Hotspots of small strokes in glioma surgery: an overlooked risk?

Background Small deep infarcts constitute a well-known risk of motor and speech deficit in insulo-opercular glioma surgery. However, the risk of cognitive deterioration in relation to stroke occurrence in so-called silent areas is poorly known. In this paper, we propose to build a distribution map of small deep infarcts in glioma surgery, and to analyze patients’ cognitive outcome in relation to stroke occurrence.
