Summary
This case study highlights a targeted surgical approach for drug-resistant mesial temporal lobe epilepsy (MTLE). Selective resection of the temporal pole and amygdala improved seizure control while preserving cognitive functions.
Area of Science:
- Neurology
- Neurosurgery
- Epileptology
Background:
- Pharmacoresistant mesial temporal lobe epilepsy (MTLE) poses significant treatment challenges.
- Early childhood onset of psychomotor seizures necessitates precise localization for effective intervention.
Observation:
- MRI revealed hippocampal structural changes and mammillary body atrophy.
- Neuropsychological testing indicated deficits in attention and visual planning.
- Non-invasive recordings failed to pinpoint the seizure onset zone.
Findings:
- Invasive monitoring identified seizure onset in the temporo-polar neocortex.
- Superselective resection of the temporal pole and amygdala, preserving the hippocampus, was performed.
- Histopathology confirmed focal cortical dysplasia (Palmini type Ib).
- Post-surgery, seizure frequency decreased, achieving two years of seizure freedom with optimized antiepileptic drugs.
Implications:
- Highly targeted resections preserving memory-critical structures offer a viable treatment option for selected MTLE patients.
- This approach balances seizure control with the maintenance of cognitive functions, including memory, attention, and visual planning.
