Aicardi's syndrome; radiologic manifestations

Area of Science:

• Neurology
• Genetics
• Ophthalmology

Background:

• Aicardi syndrome is a rare genetic disorder affecting primarily female infants.
• It is characterized by a triad of infantile spasms, chorioretinopathy, and agenesis of the corpus callosum.

Observation:

• The syndrome presents with specific electroencephalographic (EEG) abnormalities and often includes vertebral anomalies.
• Associated features can include facial asymmetry, plagiocephaly, and Dandy-Walker syndrome.
• Subnormal mental development is a consistent feature in all affected individuals.

Findings:

• The study highlights the key diagnostic features of Aicardi syndrome, including infantile spasms, pathognomonic chorioretinopathy, and corpus callosum abnormalities.
• Vertebral abnormalities and specific EEG findings are also noted as characteristic.
• The condition appears to be limited to female infants, with all cases exhibiting subnormal mental development.

Implications:

• Recognizing Aicardi syndrome in infants presenting with chorioretinopathy and infantile spasms could lead to earlier diagnosis.
• Increased awareness may reveal the syndrome to be more prevalent than current reports suggest.
• Further research into the genetic and etiological factors is warranted for improved understanding and management.
