Satellite lesions of DNET: implications for seizure and tumor control after resection.

As the seizure-RFS rate significantly declines over time, a more accurate seizure-free rate analysis using survival curves could be important for determining the outcome of DNET surgery. A thorough review identifying satellite lesions preoperatively and using intraoperative neuronavigation, electrocorticography (ECoG) or intraoperative ultrasonography is warranted to accomplish the wide resection of tumors with accompanying satellite lesions.
