Abstract:
A patient with bilateral symmetrical frontoparietal polymicrogyria is reported. Severe developmental delay, mental retardation, spastic tetraplegia, and seizures were the main clinical features. Magnetic resonance imaging revealed bilateral thick cortex with irregular gyri and festoon-like grey-white matter junction in the frontoparietal areas. Bilateral frontoparietal polymicrogyria might represent either a severe form of a spectrum of malformations involving the frontoparietal area or a further variety of the congenital bilateral symmetrical polymicrogyria syndromes in addition to bilateral frontal polymicrogyria, bilateral perisylvian syndrome, and bilateral parasagittal parieto-occipital polymicrogyria.
Insights
This study reports a case of bilateral symmetrical frontoparietal polymicrogyria, a rare brain malformation associated with severe developmental delays and neurological impairments. The findings suggest it may be a distinct or severe variant within polymicrogyria syndromes.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Imaging
Background:
- Polymicrogyria (PMG) encompasses a group of congenital central nervous system malformations characterized by an excessive number of small, unusually folded cerebral cortical gyri.
- Congenital bilateral symmetrical polymicrogyria syndromes are rare, with distinct patterns of cortical malformation.
Observation:
- A patient presented with severe developmental delay, mental retardation, spastic tetraplegia, and seizures.
- Magnetic resonance imaging (MRI) demonstrated bilateral symmetrical frontoparietal polymicrogyria, characterized by a thickened cortex, irregular gyri, and a festoon-like gray-white matter junction.
Findings:
- The observed polymicrogyria was specifically localized to the frontoparietal regions bilaterally.
- The unique pattern of malformation in this case expands the known spectrum of polymicrogyria.
Implications:
- Bilateral frontoparietal polymicrogyria may represent a severe manifestation within the spectrum of frontoparietal malformations.
- This case could be classified as a distinct subtype of congenital bilateral symmetrical polymicrogyria syndromes, adding to the existing classifications.
- Further research is needed to understand the genetic and developmental underpinnings of this specific polymicrogyria variant.
