Summary
This study suggests the insular cortex, not the temporal lobe, may cause epigastric auras in epilepsy. Surgical removal of an insular lesion resolved these specific seizure auras.
Area of Science:
- Neurology
- Epileptology
- Neuroscience
Background:
- Medial temporal lobe epilepsy frequently presents with epigastric auras.
- The precise origin of the epigastric aura's symptomatogenic zone remains debated, with both the temporal lobe and insular cortex implicated.
Observation:
- A 44-year-old male experienced psychomotor seizures preceded by epigastric auras.
- Imaging identified a right insular cavernoma, with an unremarkable ipsilateral temporal lobe.
- The patient underwent surgical removal of the insular lesion.
Findings:
- Post-surgery, the patient remained seizure-free, including the absence of epigastric auras.
- This outcome supports the insular cortex as the likely source of the patient's epigastric auras.
Implications:
- The findings suggest the insular cortex plays a critical role in generating epigastric auras in certain epilepsy cases.
- Successful lesionectomy supports the insula as a potential symptomatogenic zone, guiding future epilepsy research and treatment strategies.
