Introduction:
Mesiotemporal epilepsy (MTLE) is a clinical syndrome characterised by the association of a history of febrile seizures, a homogenous clinical presentation of seizures, temporal interictal and ictal EEG recordings and an underlying pathology that is mesial sclerosis. MTLE is the most common type of medically intractable partial epilepsy with a drug-resistance in 90% of cases.
Object:
The aim of this study is to describe the clinical, EEG and MRI findings of 9 patients with MTLE attending the outpatient clinic of Charles Nicolle Hospital.
Results:
The median age of our study population was 30 years. A history of febrile seizures was found in 5 patients. Hippocampal atrophy was found in all the cases right in 4 cases and left in 5 cases. Drug-resistance was observed in 7 patients. No patient underwent surgery.
Conclusion:
It is important in front of medically intractable partial epilepsy to evoke MTLE, to confirm the diagnosis with neuro-imaging and to propose an interdisciplinary therapeutic approach including neurologists, epileptologists and neurosurgeons.
Insights
Mesiotemporal epilepsy (MTLE) is a common cause of drug-resistant epilepsy. This study highlights key clinical, EEG, and MRI findings in 9 MTLE patients, emphasizing the need for early diagnosis and multidisciplinary care.
Area of Science:
- Neurology
- Epileptology
Background:
- Mesiotemporal epilepsy (MTLE) is the most common form of medically intractable partial epilepsy, with drug resistance in 90% of cases.
- Characterized by febrile seizures, specific EEG patterns, and mesial sclerosis.
Observation:
- This study analyzed 9 patients with MTLE from Charles Nicolle Hospital's outpatient clinic.
- Median age was 30 years; 5 patients had a history of febrile seizures.
- All patients exhibited hippocampal atrophy (4 right, 5 left).
Findings:
- 7 out of 9 patients presented with drug-resistant epilepsy.
- No surgical interventions were performed on the study cohort.
- Clinical, EEG, and MRI findings were systematically documented.
Implications:
- Early identification of MTLE is crucial for medically intractable epilepsy.
- Neuro-imaging is essential for confirming MTLE diagnosis.
- An interdisciplinary approach involving neurologists, epileptologists, and neurosurgeons is recommended for optimal patient management.

Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
