Objective:

To explore clinical, pathologic, and EEG features that may impact seizure outcomes in patients with PXAs and tumor-related epilepsy.

Approach:

Key Findings:

• 76% of patients with PXA had tumor-related epilepsy.
• The mean age at diagnosis was 32 years, with a range of 10 to 71 years.
• The most frequent tumor location was the temporal lobe (47.4%).
• Higher initial tumor volume trended towards worse seizure outcomes, but this was not statistically significant.
• Gross total resection was performed in 57.8% of patients.

Interpretation:

Limitations:

• Small sample size of 25 patients.
• Limited statistical significance for some findings.
• Potential biases in retrospective data collection.

Conclusion:
