Current Concepts of Polymicrogyria [PDF]
Neuroradiology, 2010 Polymicrogyria is one of the most common malformations of cortical development. It has been known for many years and its clinical and MRI manifestations are well described. Recent advances in imaging, however, have revealed that polymicrogyria has many different appearances on MR imaging, suggesting that is may be a more heterogeneous malformation than

Case Report: Diffuse Polymicrogyria Associated With a Novel ADGRG1 Variant [PDF]
Frontiers in Pediatrics, 2021 Pathogenic variants of the ADGRG1 gene are associated with bilateral frontoparietal polymicrogyria, defined radiologically by polymicrogyria with an anterior-posterior gradient, pontine and cerebellar hypoplasia and patchy white matter abnormalities.

A Neonate Diagnosed with Megalencephaly-Capillary Malformation-Polymicrogyria Syndrome with Mutation [PDF]
Neonatal Medicine, 2023 Megalencephaly-capillary malformation-polymicrogyria syndrome (MCAP) is a rare genetic disorder characterized by megalencephaly, polymicrogyria, body overgrowth, and cutaneous capillary malformations. It has been reported recently that MCAP is related to

MRI-based spectral analysis of fetal brain gyrification in typical development and in lissencephaly and polymicrogyria [PDF]
Scientific ReportsCortical gyrification is a key marker of fetal brain development and is typically assessed qualitatively on ultrasound or MRI. While previous quantitative approaches have characterized gestational trajectories in typically developing (TD) fetuses, only a

The genetic landscape of polymicrogyria
Annals of Indian Academy of Neurology, 2022 Polymicrogyria (PMG) is a relatively common complex malformation with cortical development, characterized by an exorbitant number of abnormally tiny gyri separated by shallow sulci. It is a neuronal migration disorder.

Epilepsy Secondary to Polymicrogyria. [PDF]
J Community Hosp Intern Med PerspectWe present the case of a young man in his early thirties who sought medical attention after a witnessed seizure episode. His drug screen revealed the presence of cocaine, marijuana, and benzodiazepines. To investigate any potential structural causes contributing to his seizure, we conducted an MRI of the brain, which revealed polymicrogyria.

Time‐Frequency Fingerprint Analysis in SEEG Source‐Space to Identify the Epileptogenic Zone [PDF]
Annals of Clinical and Translational NeurologyThis case study highlights the application of seizure fingerprint analysis in the source‐space of stereo‐EEG (SEEG) data to accurately localize the epileptogenic zone (EZ) in patients with complex cortical malformations.

Cortical Clefts and Cortical Bumps: A Continuous Spectrum [PDF]
Journal of Clinical and Diagnostic Research, 2016 Cortical ‘clefts’ (schizencephaly) and cortical ‘bumps’ (polymicrogyria) are malformations arising due to defects in postmigrational development of neurons.
