[Cerebral imaging in epileptic children: study of 140 cases]
Insights
Pediatric epilepsy often requires neuroimaging to find causes. Magnetic resonance imaging (MRI) is preferred over CT scans for detecting brain abnormalities in children with epilepsy, especially when seizures begin before age three.
Area of Science:
- Neurology
- Pediatric Neurology
- Neuroradiology
Context:
- Epilepsy affects 0.5-1% of children under 16.
- Neuroimaging, particularly MRI, is crucial for diagnosing pediatric epilepsy.
- CT scans are reserved for emergency situations.
Purpose:
- To characterize cerebral lesions in epileptic children.
- To identify predictors of abnormal neuroimaging findings in pediatric epilepsy.
Summary:
- A retrospective study analyzed neuroimaging data from 140 epileptic children (2000-2007).
- Anoxic-ischemic lesions and brain malformations were the most common findings.
- Predictors of abnormal MRI included seizure onset before age 3, psychomotor retardation, and abnormal neurological exams.
Impact:
- Highlights MRI as the optimal imaging modality for pediatric epilepsy evaluation.
- Informs clinical decisions regarding neuroimaging in children with recent seizures, excluding idiopathic epilepsies.
- Identifies key factors that increase the likelihood of detecting underlying cerebral lesions.
Background:
Epilepsy is a chronic disease, often with an onset during childhood and characterized by spontaneous and recurrent seizures. It concerns 0.5-1% of children under 16 years of age. Being much more sensitive than computed tomography, magnetic resonance imaging is the technique of choice to identify an underlying cause. CT scan is used in emergency situations.
Aim:
To describe cerebral lesions in epilepetic children and to identify predicative factors of abnormal neuroimaging.
Methods:
Authors present a retrospective descriptive study of Neuroimaging data of 140 epileptic children evaluated for a period from 2000-2007 in the paediatric departement of Sfax.
Results:
The mean age at onset of seizures was 3 years. The sex ratio was 1.12. Psychomotor retardation was noted in 75 patients. The seizures were generalized in 75% of case. Neurological examination was abnormal in 73 cases (52%). The main indications for conducting a brain imaging were psychomotor retardation (65 cases) and focal onset seizures (25 cases). Anoxo-ischemic lesions were the most frequent cerebral anomalies followed by brain malformations. Predictors of pathological MRI were an age at onset of seizure <3 years, psychomotor retardation and abnormal neurological examination.
Conclusion:
The morphological imaging is recommended for recent seizures of the child with the exception of idiopathic epilepsies. MRI is the best imaging modality in exploration of epilepsy in this context.
