Insights
Complete surgical resection of focal cortical dysplasia (FCD) lesions, guided by precise preoperative localization of the epileptogenic zone, offers the best chance for seizure freedom in children with this common epilepsy cause.
Area of Science:
- Neurology
- Pediatric Epilepsy
- Neurosurgery
Background:
- Focal cortical dysplasia (FCD) is the leading cause of intractable epilepsy in children.
- Despite its recognition since 1971 and classification in 2011, the underlying mechanisms of FCD remain elusive.
- Advances in neuroradiology and electrophysiology enhance FCD diagnosis and identification.
Purpose of the Study:
- To review the literature on focal cortical dysplasia (FCD) management.
- To focus on etiology, pathophysiology, classification, clinical presentation, and imaging.
- To identify factors influencing surgical outcomes in FCD patients.
Main Methods:
- Comprehensive literature review.
- Analysis of studies on FCD etiology, pathophysiology, classification, and clinical presentation.
- Evaluation of imaging modalities and surgical outcome predictors.
Main Results:
- Surgical management is a key therapeutic approach for FCD.
- Complete resection of the FCD lesion is crucial for successful treatment.
- Accurate preoperative localization of the epileptogenic zone is essential for surgical planning.
Conclusions:
- Surgical resection of FCD, when guided by precise localization, can lead to seizure-free outcomes.
- Tailoring surgical strategies based on FCD subtypes and localization improves patient prognosis.
- Further research into FCD mechanisms may refine treatment approaches.
Background:
Focal cortical dysplasia (FCD) is the most prevalent cause of intractable epilepsy in children. It was first described by Taylor et al. in 1971. In 2011, the International League against Epilepsy described an international consensus of classification for FCD. However, the exact mechanism causing this pathology remains unclear. The diagnosis and recognition of FCD increase with the advances in neuroradiology and electrophysiology.
Focus Of Review:
In this paper, we discuss the literature regarding management of FCD with a focus on etiology, pathophysiology, classification, clinical presentation, and imaging modalities. We will also discuss certain variables affecting surgical outcome of patients with FCD.
Conclusion:
Based on our review findings, it is concluded that surgical management with complete resection of the lesion following preoperative localization of the epileptogenic zone in patients with FCD subtypes can provide a seizure-free outcome.

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:
