Malformations of Cortical Development

Area of Science:

• Neuroscience
• Developmental Biology
• Radiology

Background:

• Malformations of cortical development (MCDs) represent a heterogeneous group of congenital brain abnormalities.
• These disorders are a significant cause of drug-resistant epilepsy.
• The imaging presentation of MCDs can range from subtle to overtly striking.

Purpose of the Study:

• To review the classification schemes for malformations of cortical development.
• To highlight the role of embryologic errors and imaging morphology in categorizing MCDs.

Main Methods:

• Literature review of classification systems for MCDs.
• Analysis of embryologic origins and imaging features of cortical malformations.

Main Results:

• Multiple classification schemes exist for MCDs.
• Classification can be based on embryologic errors or imaging appearance.
• Cerebral cortical morphology is a primary distinguishing feature in imaging-based classification.

Conclusions:

• Understanding MCD classification is crucial for diagnosis and treatment.
• Embryologic and imaging-based approaches provide complementary perspectives on MCDs.
• Further research into standardized classification may improve patient outcomes.
