Summary

This study reports on two patients with bilateral frontoparietal polymicrogyria, a rare brain malformation. Key features include severe developmental delays, intellectual disability, spastic tetraplegia, and seizures, highlighting a distinct polymicrogyria syndrome.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Clinical Neurology

Background:

  • Polymicrogyria (PMGY) encompasses a group of cortical malformations characterized by an increased number of small and gyri.
  • Previous classifications include perisylvian and parasagittal parieto-occipital polymicrogyria.

Observation:

  • Two patients presented with bilateral frontoparietal polymicrogyria.
  • Clinical manifestations included severe developmental delay, mental retardation, spastic tetraplegia, and seizures.

Findings:

  • Magnetic resonance imaging (MRI) revealed a bilateral thick cortex with irregular gyri.
  • A characteristic festoon-like gray-white matter junction was observed.

Implications:

  • Bilateral frontoparietal polymicrogyria may represent a distinct entity within the spectrum of bilateral polymicrogyria syndromes.

  • Further research is needed to understand the genetic and developmental underpinnings of this condition.
