Focal cortical dysplasia is a congenital abnormality where the neurons fail to migrate in the proper formation in utero. MRI findings may be very subtle or may even be negative, therefore a high index of suspicion is mandatory! The most common findings are cortical or subcortical hyperintensities especially seen on FLAIR-images.

Type 2 focal cortical dysplasia (FCD) (FCD2) is one of the most common causes of extratemporal drug-resistant partial epilepsy that is surgically curable.Because excision of the dysplastic cortex directly influences postoperative outcome (1 – 4), detection of FCD has become one of the most challenging aims of the presurgical work-up.. Owing to improved image quality, magnetic The power button sign, which enriches the MR semiology of type 2 focal cortical dysplasia, may increase diagnostic confidence when other cardinal MR criteria are visible or, more important, when these are lacking or doubtful. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Focal Cortical Dysplasia 2015-11-01 Focal cortical dysplasias (FCDs) belong to the large spectrum of malformations of cortical development (MCDs) 1 and represent the most common structural brain lesion in children with drug‐resistant focal epilepsies submitted to surgical treatment 2 (Table 1).Their anatomopathologic localization and cellular presentation are highly variable and affect not only cortical architecture and Cortical Thickness.

Focal cortical dysplasia (FCD) is a cerebral cortical developmental malformation which is now recognized as a common cause for medically refractory seizures in paediatric population as well as for intractable seizures in adult population [1]. There are three types of FCD recognized [1].

Lee et al (9) reported the following structural features in their series of nine cases of focal cortical dysplasia: gyral thickening (macrogyria), varying degrees of cortical hyperintensity on heavily T1-weighted images (such as magnetization-prepared rapid acquisition gradient-echo images), indistinct gray matter-white matter junctions, hypointensity on T1-weighted images, and hyperintensity on T2-weighted and FLAIR images within the subcortical white matter of affected areas.
