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: cortical thickening

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 hemisphere. PURPOSE: To determine whether the magnetic resonance (MR) imaging feature of a cerebrospinal fluid (CSF) cleft and cortical dimple can be used as a marker for cortical dysgenesis.

A sporadically occurring skeletal abnormality, fibrous dysplasia is the result of locally abnormal osteoblasts. Histologically, benign fibrous tissue of variable thickness and poorly formed trabeculae in varying amounts result in the wide spectrum of radiographic presentations. Lesions may be solitary (70%–80%) or multiple (20%–30%). 2009-01-01 2002-11-01 Abstract. PURPOSE:To assess proton magnetic resonance (MR) spectroscopy in differentiating between low-grade gliomas and focal cortical developmental malformations (FCDMs). MATERIALS AND METHODS:Eighteen patients with seizures and a cortical brain lesion on MR images were studied with proton MR spectroscopy.

Disorders of cortical formation resulting from abnormal cell proliferation might result from too many or too few neurons or abnormal cells. Microlissencephaly results from too few neurons, hemimegalencephaly results from too many cells, and focal cortical dysplasia (FCD) results from abnormal cells.

Likely Diagnosis: Focal cortical dysplasia type II (Taylor dysplasia) Type I: focal cortical dysplasia with abnormal cortical lamination. a: radial cortical lamination; b: tangential 6-layer cortical lamination; c: radial and tangential cortical lamination Type II: focal cortical dysplasia with dysmorphic neurons. a: without balloon cells; b: with balloon cells Type III: architectural distortion of cortical layer BACKGROUND AND PURPOSE: Focal cortical dysplasia (FCD) covers a spectrum of conditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary.

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].

Pericyte coverage is less in the germinal matrix vascular bed than in cortical gray or white (2003) studied MRI and post mortem tissue of EPCs had an increased risk of developing bronchopulmonary dysplasia (Borghesi et al., 2009). HD: Hip X-ray.

There are three types of FCD recognized [1]. BACKGROUND AND PURPOSE: MR imaging findings of cerebellar cortical dysplasia have been described as a new cerebellar malformation. The purpose of this study was to assess the association of cerebellar cortical dysplasia with other cerebral malformations. METHODS: We retrospectively reviewed 46 MR examinations of patients presenting with developmental delay, hypotonia, and facial deformities to Focal Cortical Dysplasia (FCD) is a term used to describe a focal area of abnormal brain cell (“neuron”) organization and development.

Greater diffusion abnormalities, as well as more marked decreases in N -acetylaspartate, were observed to occur in the patient harboring a low grade neoplasm within an area of cortical MATERIALS AND METHODS: We retrospectively reviewed the preoperative imaging data of 141 consecutive patients with histologically proved focal cortical dysplasia. We selected 25 patients with focal cortical dysplasia with the transmantle sign and divided them into groups based on the pathologic focal cortical dysplasia subtype and T1 signal of the transmantle sign. MRS-lateralisation index in patients with epilepsy and focal cortical dysplasia or a MEG-focus using bilateral single voxels Epilepsy Research, Vol. 89, No. 1 Sepsis-Associated Encephalopathy: A Magnetic Resonance Imaging and Spectroscopy Study Cortical dysplasia was considered to be an aberrant neuronal migration or maturation, and its presence contiguous to the tumor suggested that the tumor arose as an abnormal genetic control in the migration and differentiation of neuronal precursors. Our MR imaging findings showed that dysplasia was frequently associated with other malformations.

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. 2019-06-01 PURPOSE: To determine whether the magnetic resonance (MR) imaging feature of a cerebrospinal fluid (CSF) cleft and cortical dimple can be used as a marker for cortical dysgenesis.

This study aimed to determine the diagnostic contribution of cranial MRI and the apparent diffusion coefficient (ADC) in FCD. Histologic subtypes of focal cortical dysplasia (FCD). ( A ) Representative control cortex of the temporal lobe showing six layers and the gray–white-matter border. ( B ) Typical microcolumnar structure with loss of normal lamination pattern – a typical feature of FCD Ia. ( C ) In FCD Ib, typically one of the lower cortical layers is missing, as indicated here. Fibrous dysplasia can be monostotic or polyostotic. Usually it is a lesion of childhood or young adults. Not infrequently encountered as coincidental finding at later age. Central location most common with some expansion and cortical thinning.
