Unanticipated Intraoperative Seizure During Craniotomy: A Case Report and Anesthetic Considerations

Intraoperative seizures during cranial surgeries under general anesthesia are uncommon but clinically significant occurrences that require rapid identification and treatment. The rarity of such occurrences is underscored by the limited number of similar case reports in the literature. This report describes an incident of intraoperative seizure during craniotomy for tumor resection under general anesthesia. This case involved a lesion outside the cortical regions most often associated with seizure activity, such as the hippocampus and neocortex. We will discuss the diagnosis and management, as well as the broader incidence, diagnosis, and management of intraoperative seizures under general anesthesia.
