(1). Zhang et al. Superior Frontal Sulcus Seizure INTRODUCTION Focal cortical dysplasia (FCD) is a common cause of refractory epilepsy (1). Despite high-resolution MRI, FCD may be 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 . There are three types of FCD recognized . intraoperative mri in pediatric cortical dysplasia resection J neurosurg PediatrVolume 17 • June 2016 673 section, and seizure control outcome in children with in-tractable epilepsy due to FCD. This report is among the first to address the technique and outcomes following the utilization of iMRI for real-time intraoperative guidance Focal cortical dysplasia (FCD) is a well-recognised cause of epilepsy.1 We describe the case of a patient with histologically proven FCD, who initially was thought to have a malignant tumour on MR brain scan.

Cavum septum on conventional MRIWhite matter abnormalities on conventional MRI length of stay for preterm infants bronchopulmonary dysplasia MRI MRI is the modality of choice to assess patients with possible focal cortical dysplasias. There is much overlap of imaging features between the different types of FCD, and in many instances, no MRI abnormality is evident (especially Blumcke mild FCD). General features of focal cortical dysplasia include 4 : BACKGROUND AND PURPOSE: Focal cortical dysplasia (FCD) covers a spectrum of conditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary. The aim of this study was to identify the MR features of histologic subtypes of FCD that would be useful for differential diagnosis. PURPOSE: To clarify the magnetic resonance (MR) imaging characteristics of focal cortical dysplasia (FCD). MATERIALS AND METHODS: The authors reviewed the MR images of 14 patients with FCD, which was confirmed with histologic examination. RESULTS: MR images exhibited FCD in 13 of the 14 patients.

All lesions were localized to part of one Background and purpose: Focal cortical dysplasia (FCD) covers a spectrum of conditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary.
The histological features were reviewed and correlated with the MRI findings. The gyri affected by FCD were enlarged and the signal of the cortex was slightly increased on T1-weighted images.

The transmantle sign is an MRI feature of focal cortical dysplasia (FCD), almost exclusively seen in type II focal cortical dysplasia (Taylor dysplasia - also known as transmantle cortical dysplasia for this reason). However, it is not always present, seen in ~45% (range 21-72%) of patients with type II FCD.
This study determined whether fluorodeoxyglucose (FDG)-PET/MRI coregistration enhanced the recognition of CD in epilepsy surgery patients. Focal cortical dysplasia is rarely visible on a CT scan and sometimes remains undetectable on an MRI too. In other cases, the affected area shown in an MRI scan can, in reality, be larger than what is revealed by the MRI. CASE HISTORIES: We describe a patient whose clinical manifestations were compatible with RE; however, the initial brain MRI was interpreted as focal cortical dysplasia over right parietal region. 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. 2017-02-21 Focal cortical dysplasia (FCD), a common cause of medically refractory epilepsy, 1 is characterized by abnormalities of neuronal maturation, differentiation, and cortical layering.
