Summary
Dual pathology, defined as hippocampal sclerosis coexisting with an extrahippocampal lesion like cavernous angioma (CA), requires careful consideration in epilepsy surgery. Overlooking subtle hippocampal changes can lead to less favorable seizure outcomes.
Area of Science:
- Neurology
- Neurosurgery
- Epileptology
Background:
- Dual pathology in epilepsy is defined as the coexistence of hippocampal sclerosis (HS) and an extrahippocampal lesion.
- Cavernous angiomas (CAs) are potential extrahippocampal lesions that can be associated with HS.
Observation:
- This report details two cases of extratemporal cavernous angioma (CA) with concurrent ipsilateral hippocampal sclerosis.
- Subtle hippocampal abnormalities may be missed when a prominent extrahippocampal lesion is present.
Findings:
- Seizure outcomes following epilepsy surgery are less favorable when only one lesion in a dual pathology is addressed.
- The presence of both CA and HS constitutes dual pathology, impacting surgical planning and prognosis.
Implications:
- Diagnostic imaging for intractable epilepsy must consider the possibility of dual pathology, specifically CA and HS.
- Comprehensive evaluation and surgical treatment of both lesions are crucial for improving seizure control in dual pathology cases.
