Efficacy of a radiofrequency thermocoagulation strategy targeting the propagation network in MRI-negative post-encephalitic insular epilepsy: a case report
To evaluate the efficacy of radiofrequency thermocoagulation (RFTC) targeting the propagation network in a case of drug-resistant insular epilepsy following encephalitis, where MRI did not reveal lesions, highlighting the significance of this approach.
Key Findings:
SEEG indicated seizure onset in the left Heschl’s gyrus, with propagation to the anterior insula and beyond, suggesting a complex seizure network.
The highest epileptogenicity index values were localized to the left insular cortex and adjacent temporal operculum, indicating critical areas for intervention.
RFTC resulted in 44 coagulation lesions, effectively targeting the propagation network, which may inform future surgical strategies.
Interpretation:
The RFTC strategy successfully targeted the propagation network, leading to a favorable outcome in a patient with MRI-negative epilepsy, suggesting a viable surgical option in similar cases and potential for broader application.
Limitations:
This is a single case report, limiting generalizability.
Long-term outcomes and potential complications of RFTC need further investigation.
Comparative studies with other treatment modalities are necessary to validate these findings.
Conclusion:
RFTC targeting the propagation network may be an effective treatment for drug-resistant insular epilepsy in MRI-negative cases, warranting further studies to explore its efficacy and safety.
This Neuroscience Grand Rounds session, led by Muhammad Osama, MD, provides a pediatric neurosurgeon’s perspective on arteriovenous malformations (AVMs) in children, rare but high-risk vascular lesions that can lead to seizures, neurological deficits, or life-threatening hemorrhage.
Over two days, specialists across neurology, neurosurgery and related subspecialties came together to discuss advances in stroke care, epilepsy, movement disorders, neurodegenerative disease, neuro-oncology, brain and spine surgery, interventional pain management and emerging technologies.
